It doesn’t matter to me how good the LLM is at writing Go if the compiler can’t stop it from accidentally leaving another part of the software with invalid state as a result of a change the LLM is making.

What am I talking about? Nil and partially constructed structs are impossible to prevent the creation of in Go.

Sure, if you’ve got a small program with limited scope, that’s probably fine if you look through squinted eyes. But the teams I work with are working on sprawling, evolving software where the compiler saying “hey, that’s not a valid Widget” would be extremely useful and save much heartache.

An LLM does a good job of “checking” for other uses and “checking” if everything is going to work correctly, but - supposedly we’ve committed the concept to code so that the compiler can actually verify it - and Go intentionally permits invalid states of structs. This makes Go a fundamentally problematic language choice for the kind of software I work with teams on, LLM or not.

Fair criticism, it's my main gripe with Go as well - it's not strict enough when it comes to e.g. nil, enums, and type safety. Annotations are supported but they're just strings. Projects require additional tooling / linters to check for things like unchecked errors and many more "gotchas" that I think could (should?) be part of the compiler or standard tools. Trivial example, Go's compiler will error when you have an unused variable, but won't if you reuse and overwrite an error variable a dozen times and only handle it once.

But on the other hand, I suppose it makes it a bit more pragmatic - less checks makes for a faster compiler, and fast compilation was/is very high up in the language's requirements and motivation. If you want / need more strictness in your language, there's Rust, Java, C#, etc.

i never run into these issues in >100k loc of productionized llm generated elixir (nil safety, type issues). i wonder, is there something architecturally in go that makes this a particular problem?

Good point.

It's sometimes challenging to get a Rust program to compile... but if you do, it's probably going to work.

moomin 4 hours ago

The authors make some good points: compile time and test speed matter, platforms matter. But they really dodge the whole “guardrails matter” thing. And guardrails are going to win long term.

As for readability, the fact that AI-written Go closely resembles human-written Go is not necessarily a point in Go’s favour.

Not panicking doesn’t mean working as intended, the biggest issue with LLM generated code is that it will do something that’s subtly wrong not that it will crash. It anything LLMs are too careful with Golang code and litter useless nil checks everywhere e.g. for function calls with pointer receivers. That whole fear of panics is totally overblown.

And by that point a program written in go has been deployed and making money for months. These are two wildly different languages, people should stop comparing them as if they're targetting the same niche. Checks and protections that rust has aren't necessary in most cases, but increase development and maintenance time.

With test, which LLM are good at writing, you can reduce this tremendously. Even Rust won't protect you in this case, remember the cloudflare outage. At the end it is not the language, it is you intrinsic ability to architecture well your software from there any LLM can do the work.

I've found that keeping very healthy test coverage solves issues like this. LLMs are very good at validating their own implementations with TDD.

dnautics 11 minutes ago

i think they validate less with TDD; if you tell them a bare bones spec to validate they tend to write just that. if you write the test after, then their testing is causally conditioned on what was written. if you are going to write tests, it seems like teat first is way better than test last.

cookiengineer 6 hours ago

With unit tests you gotta be careful though, oftentimes LLMs skip implementations with mockups that just say "not implemented yet" or similar and then the unit tests become pointless because they start to only test internal structures for being set / not default values.

For me it helped a lot to try to make containerized end-to-end tests and a custom TestMain for this, where I am using podman to run the integration tests. This way the end-to-end tests are forced to be on network level, and you can test protocol and API quirks much easier with LLMs.

Also, never forget to write a bootstrapping docs/ folder so that you don't have to re-explain these things all the time.

So your problem is the default/zero values of properties?

In Go the convention is kind of to have a constructor pattern with a NewStruct(...) *Struct method that initializes all properties.

Also can't you build your own validator for that with the reflect package in the Add() method of your UI graph to prevent this sorta thing?

thayne 4 hours ago

> the convention is kind of to have a constructor pattern with a NewStruct(...) *Struct method that initializes all properties

But that doesn't stop you from declaring a var s Struct, and never initializing it, or making a NewStruct {}.

> can't you build your own validator for that with the reflect package in the Add() method of your UI graph

Besides the fact that that would almost certainly significantly hurt performance, how would you be able to differentiate between unitialized data and data that was intentionally set to the zero value?

TheDong 6 hours ago

The Go std library, as well as practically all go library code, is full of things that don't fully initialize all properties and things that nil-pointer-panic if you hold them wrong, so no, no matter what you do you have to deal with this wart of Go.

The go type-system is simply incapable of enforcing nil-safety without being no longer able to compile the go stdlib nor most code in the wild, so it's a quite valid criticism of the go type-system and language, and your comment doesn't hit on a valid solution.

Definitely agree with this article.

At Netflix, I lead the Go language guild. We've been seen increasing reports of users finding their AI agents writing better Go code than other languages, and increasing reports of projects favouring Go over other languages.

Two additional notes I'll add:

- Go has _great_ resources on writing good Go code, including treasure troves at https://go.dev/doc/effective_go and https://google.github.io/styleguide/go/. edit: Sorry, I forgot to add: we give these resources to AI agents and they use them to produce even better Go code.

- For a language team, Go is a dream. The `go fix` tooling, AST/SSA packages, ease of reading and writing `go.mod` (go mod edit, etc), and various other "platform"-y features make modifying Go code at scale way easier than other languages.

Uber reported that their Go code has quantitatively more concurrency bugs than code in other languages, and while to me it seems obvious from looking at Go's concurrency model, this is backed by actual data. Is there any quantitative data to back the claim that Go is better in an LLM based workflow than another popular language?

rubiquity 16 hours ago

Matches my experience as well. Go fans have conflated "can easily make something concurrent" with "does concurrency well." Go's primitives for concurrency should almost never be used directly and Engineers below a certain skill level shouldn't be allowed to use them directly ever for long running production code.

As another example, Go still has not yielded a correct implementation of Raft or Paxos while there are dozens in Java, C++, and Rust. Antithesis found some more bugs in HashiCorp's Raft implementation recently[0]. I'm sure etcd still has some kicking around.

Maybe this is a "don't throw the baby out with the bath water' problem but the general evolution of Go has been lackluster. I reach for Rust, Zig, and modern Java instead depending on the specific needs and constraints.

The best way to write concurrency in any language is a single threaded polling loop. Goroutines and messages are just as bad as all the other alternatives, which is to say they are a miserable way to write code.

But Go is also perfectly good at single threaded polling loops.

Uber has a history of blaming the tool - in Facebook fashion - rather than admitting their “talent” sucks and they didn’t hire on merit.

They used to blame Python a lot too - Python is slow compared to others but not so slow to matter that much, and you can build other services around it to handle certain work.

Facebook - who chose PHP - used to blame iOS/Obj-c as the reason they couldn’t build a decent Facebook native app in the early days (anyone remember Fastbook?)

I would take it with a grain of salt.

We've seen a pretty consistent pattern in our evaluations where Go is among the languages that models perform worst with (alongside Python), for reasons unclear. Our coding evaluations are typically measuring the foresight and planning expressed in code that is run in interactive environments/games.

This trend has been there since we started evaluating models using different languages in February 2026 and if anything, the disparity has grown in frontier models. Even Google models prefer Kotlin/C#/Rust for coming up with creative ideas (compilation success is a different story). Data at https://gertlabs.com/rankings

That being said, models love to recommend Go, and Go does have a lot going for it, especially if you are serving a public-facing website. So most of our public facing API handlers are written in Go, and we offload some of our most important binaries to Rust. There are just too many reasons not to use the languages that models think a little more effectively in.

I work at a large devsec company which uses primarily Go and TypeScript

I've found that the LLM generated Go has few mistakes, and generally isn't too obscure. But the volume of code is so high, colleagues do a bad job of reviewing it.

I've seen a lot of very silly decisions made, like returning the wrong HTTP code, or miscategorizing a metric used for an SLO, that I just don't think is helped by the sheer volume of code one has to wade through.

Ironically, we are considering migrating some initiatives to Rust, exactly because experiments indicate it works well with LLM development.

Your post reminds me of what I love about Python, we have PEP-8 which is a style guide, and it kind of shifts how you write code a bit (for the better) which is something I sorely miss in other languages, I don't get the feeling people care about style guides for other languages very much.

If you know any other language, you basically already know Go (with the exception of the channels stuff). The biggest pain is the if err != nil stuff, which I know some people like but it is suboptimal in my view. While far better than C# and Java's exceptions, far worse than Zig's model.

Go wins for simplicity. however what I have seen is companies end up going with Java coz it's simple enough - not simple as Go, but simple enough + fast enough.

though the letdown with Java is the wider ecosystem that makes unwarranted contraptions out of simple things.

Go's big advantage was M:N threads. Java's biggest flaw has been the lack of cooperative multitasking, which people worked around by mangling their code with promises. Now Java has M:N threads too thanks to Project Loom, but there's so much code written before that will never really go away.

Go is heavily opinionated on style, design, and semantics. Its design was around being as concise as possible…which means token efficient.

Yeah Go is my preferred language to code with AI. Second up is type script. Followed by Java, then Python.

joaohaas 10 hours ago

Go design is not around being concise as possible, in fact it's the complete opposite.

One of the cores behind Go is to make language simple, even if at the expense of more verbose code.

Two main examples of this is the infamous 'if err != nil' and how you handle filter/map/funcional operations.

A sort of an amateur I found Go to be really good when used with language models. Simplicity and tooling helps I suppose and I expected it to. However I was pleasantly surprised with how they are also pretty good with Flutter and Dart. Again good tooling, good documentation and perhaps not much historical baggage like a python or a PHP would have. And no stack overflow to speak of pretty much.

jdw64 17 hours ago

I have a question: why do you think Go is better compared to other languages?

After all, learning a new language takes a lot of time. While basic syntax is common and quick to pick up, mastering a language's specific mental model requires a significant time investment, which is why I've used Go before but never seriously.

My interest was piqued recently when I heard about TypeScript tooling being ported to Go, and I know it is incredibly fast. However, where do the results claiming that AI agents generate superior Go code actually come from? Is it a fair, apples-to-apples comparison?

Since Go is a very small language with only 25 keywords, the way you write code is extremely standardized. Because of this, I would assume it naturally produces a lot of excellent best practices and conventions, but I'm not sure if there are actual, direct code examples proving this

Go is really amenable to being used to write code by LLMs. New code takes time to pick up, but the LLM is a quick study.

In my opinion, it has little to do with the speed of the language. The large quantity of source code to train on is quite helpful, but I think it's something else.

There are three things that I think make it well suited to LLM authorship -

1) static typing and a quick compiler - a variable can't change type after it's declared (unlike Python) makes Go more robust compared to dynamic languages. You (almost) always know what the type of a variable is. And the quick compiling with hard-stop errors means that the LLM gets a solid signal for each round.

2) It's quite opinionated, syntactically. There is generally one way that Go lang code is supposed to look. That means it's pretty easy to read as well as write. The lack of things like operator/method overloading make it an easy language to reason about.

3) the stdlib and limited dependencies. Dependency trees tend to be shallow, and because of the static linking (by default), you can generally be confident that what you wrote will run.

zarzavat 7 hours ago

My calculus is very simple these days:

If I care about performance, use Rust.

If I care about iteration speed, use TypeScript.

If I want a script or numerical code, use Python.

LLMs are better with Rust because the more expressive type system provides stronger guardrails especially when writing multithreaded code. Go is almost the worst conceivable design of a programming language for LLMs: powerful but weak guardrails. Only C and C++ would be worse.

LLMs don't struggle with the low-level lifetimes like humans do. They struggle with the high-level view because of limited context windows. That's why you want a powerful type system to enforce those global constraints. Go ain't it.

I love the sleight of hand this blog post tries to pull off here. It doesn't matter than Go isn't fun to write because the AI is doing it now! Yeah so it sucked for the last twenty years? I know the main thesis is that Go is holistically good at software engineering so its weakness as a programming language is minimized. I've made a similar arguments that coding agents push the burden more into the other aspects of software engineering. But like, we all see what Google is doing here right? They want to declare that the rules have changed so Go's weakness transmutes into a strength. I'm also not buying it.

I agree with you here and I think you raise several good points, such as "Go's weakness transmutes into a strength" (allegedly). Indeed that makes no sense for Google to try to claim that.

Your other point is even more interesting, e. g. "before AI, Go sucked and nobody used it" - now this may be an exaggeration or simplification, but it is a great observation nonetheless, because Google suddenly tries to connect Go with the rise of AI, almost as if AI could not have risen without Go, which is indeed very strange as an argument to make by Google here. This also reminds me of Google promoting Dart/Flutter before giving up on this and preparing to send it (eventually) to the infamous Google graveyard at some point in the not-so-distant future.

It pulls no such sleight of hand, and you have invented a wholesale strawman.

It's also simply poorly informed. Go is a fantastically enjoyable language to program in. In many ways that has been a bit of its curse compared to languages like Rust (which is legitimately a not fun language to write it, and which AI tools are also very good at writing), because keeping the language simple has hobbled some edge cases.

I don't write a lot of Go as my professional life has pushed me more to Rust, but Go and Object Pascal are easily the two most enjoyable languages I've ever developed in.

Havoc 15 hours ago

This would have been more credible coming from someone other than the creator of the Go language.

I'm personally leaning into rust for LLM. The whole fussy compiler & errors surface at compile time seems IDEAL for LLMs for me. Hammering compile with tokens is a way better strategy than trying to deduce where stuff may fail at run time and try to catch it via tests.

Tokens are cheap, surprises at runtime are not. So a super anal compiler is what I want. I've looked at lean4 too as the logical next step but not confident I can guide an LLM competently enough for that.

igravious 14 hours ago

fwiw I have a bunch of LLMs writing first Lean code and now Agda code.

My observation. LLMs find reasoning about Agda as difficult as I find reasoning about C code. I've thrown a lot of gnarly C and Ruby code at all sorts of LLMs and they have only gotten more and more impressive as frontier models have gotten stronger. With Agda, they're like "hmm, tricky" whereas for me it's an impenetrable fortress. I've asked them why they find Agda so much more difficult to write (and why they have to iterate and reiterate many many many times until they get to a destination whereas they can one-shot and two-shot C and Ruby and they tell me its the multiple competing constraints. GLM is hilarious, it flat out refuses to write Agda code but it reads it well enough. They all read it well enough. Fable is obviously great at it. And Opus 4.8/5.0 are great (if they stay on track and don't sneakily go their own way) but they're too annoying to talk to. On balance Kimi K3 is the best balance of not annoying, relatively cheap, and strong -- great model all round tbh.

So yeah, interesting I've discovered the limits of their ability coding-ability-wise. None of them are that good at designing/aesthetic judgment/architecting so thankfully they still need me in the loop.

A huge amount of it is also the amount of training data. Agda will have little training data so the result will not be nearly as good.

A bit funny, because I thought... Hmm, so LLM's find Agda natural?

My point being... It's a matter oh habit. After writing C firmware for more than a decade, I can read C easily. I might have to think of some parts and trace the code. But I can grokk it and hold the thing in my head. With Rust on the other hand, I just don't feel it as well. I am afraid writing C gave me brain damage and restricted the lens I can see the world through.

I disagree.

LLMs fail to produce bug free concurrent code even for very simple cases.

Golang lacks the ability to build descent abstractions, not even mentioning the wild west of additional tools and libraries needed for non trivial micro services.

For me it is a red flag, that LLMs allow people to produce more bad Golang code faster. This is only optimization for companies which can afford enough software developers to review the excessive amounts of code needed to solve trivial problems in Golang, which are builtin in every descent programming language and/or framework.

Use LMMs and use the right programming language. This might be Golang, but most probably it is C#, Java, Python, Ruby or even PHP. (Or Rust, C, D, ...)

Groxx 9 hours ago

Broadly agreed, the concurrent Go code I've gotten out of them has been absolutely riddled with issues, and they're even worse at writing tests for it. They can get tutorial-level code on the first shot almost always... but tutorial-level Go code is often rather unusable in production due to missing error handling or observability.

Go's generics are getting a fairly important improvement soon though! Generic methods, finally! It should help open up some more ergonomic patterns: https://tip.golang.org/doc/go1.27

Ask them to debug. LLMs are acceptable at writing code, but they're really good at spotting bugs in code that's already been written. What kind of results do you get if you tell them to look for bugs with a clean context subagent?

In my experience, LLMs are excellent at finding concurency bugs.

I like Go but a couple of these "advantages" wash out when you add the scale and typical usage patterns of agents.

| Go is Readable / Go is Maintainable

It's true that Go, as a low-magic language, tends to be very same-y looking across projects, which is incredible for being able to reliably understand your dependencies' source code. And its tooling is world-class. I love this about Go.

But in practice I've found that, working in a monorepo with multiple teams, contributors that don't have cross-team legibility as a priority will just write SO much more code. And with business logic, often the fact that I can read the code on a line-by-line level doesn't matter if I don't understand the wider context to know how something might effect spooky action at a distance.

Pre-agents, I witnessed a fast transition from a codebase that I could mostly hold in my head to one where large swathes of it had been written and rewritten until they were unrecognizable to me. Now we have agents and, since they are still mostly not good at software engineering in-the-large, the process of knowledge debt accumulation (and ofc tech debt accumulation) in a codebase accelerates tenfold without concerted effort in the other direction. Go being easy to read does not intrinsically help with that.

I'd argue Go is not on a "Pareto frontier" and that no matter how you value the various attributes of programming languages, a fair assessment will never select Go.

A simple example is: if you highly value language popularity; Go is not most popular. If you highly value a type system that catches errors; Go's type system catches fewer errors than others. Etc. There is no weighted sum of attributes that will select Go--that's my argument.

runjake 16 hours ago

Here's how my assessment selected Go (long before LLMs):

- I had to write a moderately complex program. I didn't want to do it in C, and I didn't want to learn Rust.

- So I spent roughly about 2 hours becoming familiar with Go and playing around in Go playground. I decided that this would work.

- And then I got started on my program and I was immediately productive and that software is still running today, along with all the other stuff I've written since then.

Programmer productivity is excellent with Go. And it has a thriving ecosystem. Of course, some things could be better, but I don't really have much issue with it's error handling or types.

Something doesn’t need to be the best at anything to be on a Pareto frontier. And (usually) no one chooses on a single dimension; they choose a point in many that maximizes distance from zero, scaled by their preferences, if you are thinking of it like a frontier.

Yes, you're technically correct (the best kind of correct).

I guess if you consider enough attributes or "dimensions" then any programming languages will be the furthest in some direction, including Go.

Is there a language that you would argue is at least as good as Go at everything and better than Go in at least one thing? That would be the most straightforward way to argue against its Pareto optimality.

I'm not GP, but for me that would be TypeScript. TypeScript's tooling is as good as Go's across the board, it's very readable, it's a simple language, it has very few footguns, and it compiles fast. But it has better type safety than Go.

This isn't an exhaustive proof as no language will every be fully Pareto optimal in practice (it's just not possible, there are too many dimensions), but I'd argue it's at least somewhat close.

Go is relatively easy to learn, and the semantics of the language make it more difficult to write "clever" code that's difficult to understand.

That's the main selling point, with a secondary point that it statically compiles so you don't have to do a whole Python/JS distribution thing for CLIs.

Java feels like the closest contender here, although it really sucks for CLIs due to start up times. I don't think it's the easiest to learn either, but I've never tried all that hard.

It only really makes sense to me at org-scale, though. I think you raise a very good point for individual projects, I too normally don't choose Go for that (unless I need compilation to make distribution to myself easier on corporate laptops).

I wouldn't take language advice from a Product Manager and Chief Evangelist from anywhere - and especially not Google.

Having said that: my opinion is that LLMs thrive by working in a tight loop. Unlike a human, they thrive with more and tighter constraints (and the better models are obviously far better in this regard).

I want to ditch the things that made writing code easier due to the limitations of humans, and embrace something that an LLM can leverage for better results. For me that means: an especially rich type system, (ideally pure) functional code, efficient systems-level performance and leanness. Good error messages that guide the LLM incrementally.

Go does not provide much in the way of those 3 desires, so calling it "ideal" with nothing aside from anecdotes to back that up is not compelling.

I will leave this prediction here and maybe come back in few years:

1. JS is mem-safe, single-threaded, and there are lots of training data. Easily my first choice. I'd put Python here as well, although I don't like it personally. Both should be used with "avoid external deps" in your AGENTS.md

2. Go might be a good second choice. Simple language, IMO good primitives for concurrency, well-designed std, therefore smaller potential for supply chain attacks.

3. Elixir/Erlang, little training data but rising. Safe language, safe concurrency, immutable, scalable, there are some many advantages... It has been avoided because it's different but that could change drastically in the age of LLMs.

4. Rust is probably next choice, along with C++, because while Rust is safer, the language is quite complex. C might be here too, there is a lot of training data, but every project is different and the language is very unsafe.

5. Zig, I really like the language, but it is terrible for LLMs, mainly because it's constantly changing, and the std is also under-featured and IMO weirdly designed. It's a fun language for hobby hacking, which I believe is not going anywhere, it's just not going to be something you will be payed for.

I mostly use Elixir and JS, and I'm constantly surprised by how much easier and better the code quality is in Elixir, especially given the much smaller training data.

At work, we use C#. I'm shocked at how much worse it is. I've also used a bunch of Python, but I still feel the quality isn't as good as the codebase grows, but I didnt put as much effort trying to improve it.

> Is it better than zig if you are outputting minimal wasm deliverables?

Which tradeoffs are you willing to accept? Zig (along with several other languages) is superior in a lot of ways for that type of job, but I still settled on Go for a particular minimal WASM (browser) project. It wasn't my first choice, but it was where I ended up because LLMs kept going out to lunch in other languages and I didn't have anywhere close to the required budget to write it by hand. I read some comments like these about Go in the past so the Go attempt was mostly a contrarian Hail Mary after so many previous failed attempts in more technically well suited languages and... it worked! Shockingly well.

It still isn't my first choice for it, but having something useful with happy users beats technical imperfection every day of the week as far as my needs go. Go really did show its worth as an LLM target for that particular workload. Whether or not that is reproducible for any other project remains to be seen, but there seems to be a growing sentiment that echos the same. There just might be something to it.

I keep seeing these language specific proclamations, and they are annoying and reek of inexperience to me.

I’ve had a great time doing LLM assisted coding in Zig, and it seems comparable to the generic Typescript/React I do at work.

I don’t doubt simplicity and good PL design pay dividends, but everyone’s favorite language can’t be the silver bullet in our new LLM world. Things just don’t add up, and I keep seeing it for Erlang, Gleam, Lisp, C, Rust, Go, TypeScript, Python, etc.

And to pick on Go a little bit, I don’t think it has any unique qualities that make it better for LLMs, where I think you could make that argument for other modern languages that offer new features leveraging their compilers and enforcing more correctness guarantees.

> leveraging their compilers and enforcing more correctness guarantees.

The counter argument here is that these checks cause slower compile times and were designed to prevent common mistakes humans make.

If models get good, they may not need the same checks human written code needs. For example, frontier models already will virtually never produce a typo.

Humans need time to think, but a model’s bottleneck is in how quickly it can verify its work. Slower compile times hurt a models ability to iterate.

I don’t think we’re there yet (and we may not get there). But there is an argument to be made that languages with faster compile times may be better for LLMs in the long run than languages with strong checks but slow compilation.

Probably both, but I have to add: I agree with the post. I've done a ton of agentic development using Go over the past 6 months, and it hasn't let me down. You may ask "why not Rust, or Zig, or ____?" The reasons boil down to this:

- There's a lot of Go code out there which the models have seen, so they know how to write it.

- Go has an exceptional standard library, so you don't need to drag in 100 dependencies to create a simple web app.

- Go compiles extremely quickly for incremental builds, which really matters when agents are building and running tests constantly.

- Go has a goldilocks blend of performance and safety. You get a good type system and excellent runtime performance without forcing the model to spend cycles fixing Rust lifetimes or Swift concurrency issues for a marginal incremental gain.

- Go is relatively stable, so the LLM's memorized knowledge is still pretty fresh (as opposed to something like SwiftUI, where the API changes rapidly).

dralley 17 hours ago

I don't think Rust is particularly worse than Go in any of these respects.

- LLMs have clearly been trained on a lot of Rust as well

- Compile times are counterbalanced by strong compiler with excellent error messages, and "cargo check" can catch many issues without a full build.

- If you're willing to accept Go levels of performance from Rust, there's nothing preventing you from using copies and clones rather than borrows, which makes most code dead simple.

- For most major dependency types, there exists a clear "winner" in terms of community adoption, so the fact that it's not in the stdlib is not that problematic.

I use go for work and basically 100% agent-driven. I'd say using go with agents is a lot better than without. We use to have a consistent source of production errors where we forgot the pointer case in type switches (we'd pass a pointer to a struct where a concrete struct was expected and vice versa). AI hasn't made that mistake once in my experience.

That being said, the whole thing about go being "readable" is a little bit of a two-edged sword. Sure, it's straight-forward to read, but it's pretty verbose. And agents are good at producing a lot of text. The problem with reviewing go code for me is to see the forest for the trees. Subtle misunderstandings often hide in the vast amount of code that you have to read through while keeping the whole context in your head.

Anyway, it turned out that Go ironically makes it difficult to collect per-test-case coverage data. In spite of the standardized tooling it looks impossible to write a standardized collector that would run on most codebases. In hindsight using another language would have been a better choice

Plain JavaScript is the ideal language for AI coding. It's very good with complex architectures.

I think partly it's because the training set contains a lot of JS, but also because complex software written in JavaScript must have impeccable architecture in order to exist at all.

It's rare to encounter a complex, functioning JavaScript application with bad architecture. I've never met any engineer smart enough to maintain a large spaghetti-code JavaScript project.

I've had a really terrible time getting LLM to properly handle errors as return values. It seems that bubbling up errors, in a side channel, to a contextually relevant point in the code (exceptions) seems MUCH easier for LLM to reason about/implement properly.

Maybe my problem is I'm using a language with exceptions, so trying to go against the statistical grain, with return values, is just too much.

frollogaston 14 hours ago

Exceptions are inherently better for high-level code, where basically every loc can fail and 99% of the time you only want to bubble that up. You only want errors as values in systems code, where exceptions would be landmines. Rust and Go both did that because they were at least originally designed for systems code.

Also, Go makes it way too easy to accidentally swallow an error. Rust doesn't have that problem.

The killer feature of golang for LLM dev is the tooling.

forbidigo is what allows me to keep ambient config out of my app, and restrict file access to a small set of paths. The coverage tool has "nocover", so you can guarantee that every realistic path is exercised at least once ("100%" code coverage, which is not a marker for testing completeness, but rather for flagging code you forgot to test). Linting is really good as well.

The only thing I haven't found is something to enforce error handling. Rust is better for error paths because you're not allowed to ignore them.

> Linting is really good as well.

Maybe we are using different tools (or we've set it up wrong) but I'm consistently surprised at how slow Go's linting is (using golangci-lint). Takes nearly 5 minutes on our codebase after any change (which means I just don't run it locally or in-editor). It's remarkable how poor the experience is after using tools like Python's Ruff (instant) or Rust's Clippy. I'd have expected a fast, default setup that I could tune.

Event JS's Eslint, which runs in actual JS, takes 21 seconds for a full sweep (which I don't normally run, since the in-editor hints are so fast)

It's surprising, because so many of Go's dev tools are so well thought out!

errcheck, generally as manifested in golangci-lint, ensures you can't forget to do something with them. It would be odd for you to know about forbidigo but not errcheck as the former is much less widely known; is there something that errcheck doesn't do for you?

It's worth pointing out that "discard this error on purpose" is a legitimate form of error handling, so "enforce error handling" can't really constitute banning that. That's not a Go statement, that's just true in general... it is sometimes valid to just ignore the error, because there's nothing useful to do with it anyhow. I would agree the ignoring should be explicit, but it is an option.

Multiple languages can have a degree of understabillity, but what matters most is context, because sometimes we need to code in a way to solve a specific problem like performance and it should be kept as is.

Another side subject I should add is about test coverage, although code is cheap, mainly because AI, guarantee that new changes to a stable code should continue to work as expected.

I worked on a few go projects with bad structure and some of them with really low test coverage (e.g. 8%), so part of the post resonates with me about we as software engineers should pursuit good architecture and other skills to allow long term maintenance.

The issue I always had with Typescript, was that LLM's like to find the easiest way to get a job done on a micro level (they seem to like to find the hardest design patterns to implement on the macro level tho, but language agnostic). What this means for Typescript, is unless you place guardrails everywhere, they'll cast their way out of a compiler problem with as any, or as unknown and then casting later. You either end up with readability issues, or runtime issues leaking out.

Might be a skill issue, but I got frustrated with it on new projects constantly.

That's not really a typescript thing though, just an LLM thing.

jpgvm 2 hours ago

It really isn't.

Poor correctness guarantees, especially w.r.t concurrency. Nil pointer. Why.

LLMs are like a magnifying function. Whatever you put in you get back 10x over.

In the case of Go, in goes verbosity, Nil pointers, poor concurrency and synchronisation primitives (or poor performance of the safe ones, leading to sync.Mutex everywhere anyway). Also Go prioritises local readability over global understandability which is a poor tradeoff for LLMs with limited context windows.

So the LLM generates absolutely monstrously huge amounts of very hard to review very likely incorrect code.

No thanks.

Rust > Go.

In goes powerful, terse type system. Strong correctness guarantees not just around memory and pointers but also data races. A tendency towards using the type system to model invariants instead of relying on procedural guards and runtime assertions etc. Producing denser code is an LLM feature, it increases context window efficiency. Similarily the typesystem takes something that the LLM can spend a bunch of thinking tokens on to create a powerful global constraint. This fixes the global reasoning/context problem by pushing it back onto the typesystem.

Depending on the quality of your robot you will get different quality of code out but the ceiling is much higher. With Go better robots don't help much, even the highest quality robots output insanely verbose Go. Sort of just like with people... sort of like the language was designed as a lowest common denominator tool...

For a seasoned Rust programmer the output probably won't be hard to review, it will be easy to look at the types and either say "yeah that should probably be correct" or "no robot, do better".

You simply can't actually review the output of the slop cannons with Go, there is too much, looking at a struct tells you almost nothing about how correct the thing likely is, etc. The tests don't help either because there is going to be 10x the usual amount of those too so trying to review those for correctness is the same Sisyphean endeavour.

YuechenLi 16 hours ago

I wouldn't say Go is IDEAL for AI coding, but it certainly has the case for one of the best programming languages that currently AI uses. Go definitely has its share of problems for human authors because it's so verbose and boilerplate heavy, which means it's less of an issue with LLMs than it is for human coders. Rust is comparatively worse, because LLMs don't make the same coding mistakes that humans do that justifies the existence of the borrow checker, it only seems to get in their way, and they spend more time fighting Rust's infrastructure than writing code.

The biggest barrier to Go adoption seems to be Google's internal resistance to migrate C++/Java code bases to Go and refusal to admit that Go is an amazing application programming language and not really a systems programming language for bare metal OS/driver work. For example, one of the biggest barriers to Fuchsia adoption has been Google asking people to commit to Dart, I think Fuchsia would have fared a lot better as an Android successor/alternative if the official applications programming language just been Go.

(BTW Carbon isn't even a real programming language, it's still somehow stuck at 0.0.0.0 after 4 years of development which is honestly insane.)

Oh, so, little bit of self-promotion: if you like Go but is frustrated with the ergonomics of it, I would ask you to try out the programming language I developed, Oct, for LLM coding which you can kinda think of as my attempt at making Kotlin for Go's Java: It uses a codegen compiler and compiles to a plain Go binary, so it runs on everything that Go runs, and there is a lot of extra features as well: Rust style exhaustive tagged/payload enums/`match`, C#'s immutable records updated with `with`, exhaustive error handling easy parallel concurrency, xUnit.NET style unit test harness, TypeScript style compile time constraints, F# like SI unit system, Go code generation metaprogramming, etc. Would love to have some Go experts here on HN take a gander at it and provide some feedback.

I have found exactly the opposite to be true: as always, people think they can write safe concurrent code without the machine checking them and end up getting it completely wrong in lots of subtle cases. Except the problem is now much worse because you're not even writing the code, or in many cases, reading it. I prefer a language with a type system that saves me from the review burden of closely checking (and pretty much always finding issues in) concurrency invariants. And even tells me a bit more beyond that about what the code is intended to do.

That's a pile of bollocks, pardon my French. Source/proof?

And to the contrary:

I've been working on a TS codebase that calls into C++ native/wasm-compiled code for six months now. The code is mostly LLM written.

Over these last six months we had four use-after-free and two other ownership-related bugs in LLM-generated TS code.

Whereas we had zero issues of any such kind with LLM-generated Rust code that sits in another two native/wasm-compiled metacrates we use.

LLMs are not much better at ownership tracking than humans.

Especially if resource acquisition and release are far apart in code and/or somehow nested/stacked/non-straightforward.

afdbcreid 14 hours ago

The problem with ownership tracking is that it's global. Humans are bad with global things, linters too, but LLMs are exceptionally bad at them due to the context window and (currently, at least) not knowing enough where to search. So yes I'd expect them to make the same mistakes as human and even more frequently.

YuechenLi 13 hours ago

I'm curious on what you mean by "TS use-after-free", because as you obviously know, TS is GC'd. I don't have access to your codebase of course, but it seems to me that it is an FFI/native code boundary lifetime bug in the binding between TS and C++/WASM, not part of the TS managed memory. Comparing TS to native C++ FFI and/or manually managed WASM resources interface vs Rust + Rust ownership checked resources interface is kinda comparing apples to oranges here.

And as other commenters here have said, Rust's main issue for LLMs is infectious lifetime propagation, where the borrow checker knows you violated a lifetime constraint but doesn't tell you how to actually solve it, so LLMs get error messages like:

  borrowed value does not live long enough
  cannot borrow `x` as mutable because it is also borrowed as immutable
  lifetime may not live long enough
And instead of trying to reason through the ownership graph, they just take the shortest path to get these things to go away by bypassing the borrow checker entirely, which defeats the entire point of using Rust to begin with.

If the premise of the article is true, and I think that it is, that's quite the downside for AI coding with go. The premise being that reviewing now plays much more of a role than writing.

Personally, I'd rather review, say, a ruby oneliner that extracts specific row values from a csv file with filter_map, compared to 40 or so lines of go, many of which I'd have to check individually for possible mistakes.

ameliaquining 16 hours ago

Go doesn't have any kind of story for incremental migration from C++ or Java; you are talking about rewriting all those codebases from scratch, which is an obvious nonstarter as long as engineering resources are finite.

IIUC Fuchsia uses Dart mostly for UI stuff and Go has never really tried to be competitive there? I don't see much of a reason to suppose this is a serious bottleneck to Fuchsia adoption, as opposed to the obvious reasons why it's hard to displace an existing OS with a huge install base.

Sure, what I mean by that is that LLM makes different kind of mistakes than humans, they usually take the shortest direct route to accomplish their task. You can see that with the Bun Rust rewrite, I don't think any human coder would put as many `unsafe` and `Clone()` and `Arc<Mutex<T>` in their code, so a lot of time, they would just attempt to bypass the borrow checker if they see it get in their way.

I think boilerplate & verbosity is an even bigger drawback with LLMs than human coding since context rot and "Lost in the Middle" phenomenon has so much effect on code quality

It seems that LLMs benefit from semantic and syntactical density

So in terms of the mainstream languages, what would you say would be the most ideal language? (At least until Oct takes off!). Perhaps modern Java? .. Or even Zig?

YuechenLi 16 hours ago

C#, only because of dotnet ecosystem and tooling is great. TypeScript is a dark horse candidate, it's a great language with a great ecosystem trapped by JS tooling, and most of all, NPM. Rust is fine if you just tell LLMs to use short borrows only. I wouldn't even say Oct is the most ideal language, it's pretty good at getting LLMs to do science, but probably isn't the right language for all applications.

I have some very heavy criticism for Zig technically, because their whole thing about "no hidden control flow" becomes "shove all the hidden control flow into a second hard to debug runtime that runs at compile time", and manual allocation for everything is incredibly tedious and hard to keep track of in production code. I mean, C++ wasn't ALL wrong, there was a reason that templates exist in the first place, and having the entire generics model be just comptime isn't really a decision I agree with. The way I see it, Zig would probably find a niche as a language that configs C/C++ codebase at compile time instead of the C replacement they want it to be.

There are two more languages I have in the Oct repo, SDSL-V for SPIR-V shader/compute kernel authoring and Concept/Vulkan because the 20k line C Vulkan Prometheus runtime for GPU compute that we built is getting kind of unmaintainable even by AI that making up a new programming language to strangler fig refactor it is honestly the least bad option.

keeda 13 hours ago

I haven't touched Go in over a decade (since before generics!) but I can see why this would be true. My theory is that LLMs absolutely love very tight, focused context. Go inherently restricts how many abstractions you can stuff into your code, and more abstractions tend to make the context a lot more complex and noisy. So LLMs love Go code because it keeps things simple.

The thing about Go, which some have complained bitterly about and others (and TFA) have touted as a strength, is the limited expressiveness of the language (hence my remark about generics!) This is what restricts the number of abstractions in Go code, leading to more verbose but much simpler code all around. Choosing between simplicity and expressiveness is a matter of taste, but also organizational dynamics; for larger organizations which require a large amount of context shared amongst a large pool of employees, it's better for the code to be simpler and locally understandable. As TFA indicates, this has been a guiding principle for Go.

I think what is happening with AI coding is similarly related to context. Consider that while more expressive languages enable more abstractions, they can make the code more concise, but critically, this also spread the logic around. E.g. in large Java codebases you will find deep inheritance hierarchies with class and method definitions spread around a dozen different source files and JavaDoc references.

This necessitates finding and stuffing a lot more information into the context for any given task, a lot of it irrelevant and all of it more complex, because it requires making multiple hops of reasoning to figure out the logic. On the other hand with fewer abstractions, all the necessary code and logic though verbose is right there. It's much easier for a human and an agent to follow that code.

The difference is a human gets tired reading a lot of code, which is what pushes us to devise more abstractions, whereas an AI does not get tired.

I get the sense that if a context is stuffed full of highly relevant information, the agent will perform well regardless of the size of the context window. But the moment you pollute it with noisy irrelevant information, performance will drop regardless of the size of the window. (There are some papers showing this effect IIRC.) Hence simpler code, as encouraged by simpler languages like Go, are more amenable to tighter and simpler contexts, which work better for AI.

Purely anecdotal, but my experience has been that LLMs generate low quality python code. It's spaghetti code on par with what I've seen when companies I worked at tried offshoring development. It's basically what you get when you give bad or incomplete specs to a team of inexperienced programmers with poor development practices. It's usually good in small chunks, but it gets extremely sloppy as the scope of work increases and more decisions are introduced. Interestingly, I've seen LLMs generate good clojure code.

My guess is it comes down the the training data more than anything else, although I suspect functional languages will fare a little better. At least that's been my experience. There's undoubtedly a ton of python code in the training corpus and portions of it are of dubious quality. Niche functional languages likely have a smaller training corpus where a larger portion of it is better quality.

It is unclear to me though how much of your expectation might be set by the training dataset.

For example, Python and Typescript have the most amount of codebases and training being done on. So I feel as if that plays a part into the overall thing.

Languages which are more niche have genuinely hard times (Try arturo lang for example), so it depends on a lot of things/nuance, or well that has been my experience trying something recently.

My personal opinion is that if each language has the same amount of training. Golang comes close but the first might be Elixir. I have seen Elixir language perform really well with LLM's with magnitudes less training dataset. There have been some studies which had Elixir as the number one language for such tests iirc.

Gleam is a new addition as well and I feel as if it could be good and its another interesting option as well with more type-safety and an interesting language overall.

- BEAM makes monoliths sexy. You don't have to worry about a bunch of microservices, just focus on using proper process division for modeling your problem. - Debugging on the BEAM is first class. Drop into an interactive shell, pull up telemetry, or recon and hammer down on where your live app is slowing down if your metrics have a blindspot.

I could go on and on. I'm constantly blown away every day by the amount of time and effort and all of the sage learnings in distributed computing problems that came out of Ericsson that became the foundation of erlang + OTP + BEAM and in turn elixir + Gleam.

Go was designed as a systems language. They turned it into an applications language too, I'm guessing because turns out the greenthreading was uniquely good for that. But now it's awkward. The pointers and errors are not how you want an app lang to work. And LLMs struggle with error handling even more than humans.

Even as a systems lang, the error syntax is the worst part of Go. Can they at least put the ?/! syntax like in Rust instead of this "if err != nil" spam every other loc?

I am not saying this is a rationale used by many other people either, mind you, but Rust has been taking strides (not that I am a huge fan of it either but for different reasons) and it seems to me as if Rust has finally now more momentum than Go, which I find interesting. Again, this may be a correlation rather than any causation, but I can not help but notice it.

Personally I find Rust a lot harder to read than Go.

If you're going to have an agent write most of your code readability is very important.

_verandaguy 17 hours ago

I'll qualify this from my POV (which may be different than GP's).

Go's historic maintainability strong suit has been its simplicity and consistency. The syntax is, relatively speaking, lightweight, the language invites complexity through composition, and information density for any unit of code is typically quite low (which isn't necessarily a bad thing).

In my opinion, though, these are all drawbacks, and Rust addresses all of them. It's syntactically and semantically much heavier, leading to its oft-maligned steep learning curve. It has, uniquely among the major languages, I think, a syntax for expressing variable lifetimes (with its own unintuitive semantics). It stuffs lots of abstraction into a hodgepodge of terse semantics and punctuation.

It sucks to read, until you get really used to it. Then it tends to read really quickly, and, at least for me, it's easier to reason about a conceptually-broad piece of logic if I don't have to jump between different locations in a file, a module, or a package to do it.

With Go, I find it more difficult to get into a flow state, and easier for my eyes to glaze over when looking over large diffs.

It's not lost on me that these are purely subjective arguments, though. My preference remains with Rust, and that goes back to before I used LLMs.

I'm also aware that Go is very prescriptive about how you write it; it's explicitly opinionated, and Rust doesn't have that. It means that most Go code bases will look more alike. I consider this an anti-feature; I believe code should be able to conform to the problem space or product and a good team will find the best way to do that.

For whatever reason, maybe not even logical ones, Go repulses me. I don't know why exactly, I like the idea of Go, but the aesthetics rub me wrong.

I think it's the use of pointers and "if err != nil {}" error handling spam. It reads as a highly compromised imitation of Python and C rather than a solid execution of some other idea.

Rust is not the most beautiful language out there but it doesn't trigger any such reaction for me. The ? operator and "match", which I use constantly, more than compensate for some of the sigil noise which I barely need to look at much less write most of the time. So Rust wins on that comparison for me.

The "func name() -> retval" syntax also grew on me. I like the fact that Python type annotations copied that approach, and C-style declarations look ugly to me now. Same with C-style /* */ comments.

It's a matter of expressiveness, Rust expresses more.

E.g. make a table that's 3x3 is easier to read (Go), but the equivalent line in Rust would also include material, angles, height, etc. because the type system encodes much more information.

Though I always found Go to be significantly harder to read than Rust. Sure Rust has some crazy syntax at the edges, but Go makes it very hard to know where imports come from (and thus what they do), and the imperative style + lack of clarity about mutability makes code much harder to reason about.

Obviously, I get why you feel humans still reading code is important, but if you look at the progress of AI for the past couple of years, that gap is closing. The trendlines speak of a future where it becomes less and less important.

This was exactly what happened with writing code. Now most people don't write code.

Personally, Rust or Typescript both happen to be better than Go for me. TypeScript has better type-safety and tooling for user-facing apps, and Rust has better type-safety and tooling for algorithmic stuff or stuff that needs to run fast.

I guess the difference in compile times doesn't matter enough?

ramoz 17 hours ago

idk. In my experience the build/compile experience has been far worse esp for fast iterating. Even concurrency models did not seem as intuitive as Go's. Im no systems expert - have deployed practical and performant distributed systems though.

Zig seems to have more closely aligned with what Go devs prefer.

Go doesn't have memory safety issues because of its GC, while Zig has UB problems. Zig might have slightly better performance, but I don't think choosing a language without memory safety is a good idea

Ignoring performance for the moment (because most situations are bottlenecked on something else), why is rust better?

threethirtytwo 17 hours ago

I agree, but this doesn't justify anything. Saying rust is better because it "just is" won't convince anyone. I'd like to know why you think it's better.

Rust compiler is a tyrant. Type system is strict. Borrow checker is relentless. LLMs can't slop too much without being beaten up by the compiler.

except Rust is HARD while GO is super easy.

Rust makes you solve many of your problems upfront, which is a nice feedback loop for using with an LLM. Go does much of this too, but I feel Rust is more experessive and takes the frontloading a bit further.

It's not that hard.

“…requires opinionated simplicity…”

Of course it can’t just be simplicity, it has to be “opinionated” simplicity. Rolls eyes.

Because Go is an absurdly verbose language that hates to the core the idea of expressivity because it prides itself on being dumb.

Let me share a hot take. I am deliberately taking this somewhat to the extreme, so please attack the idea not the person. Looking for thoughtful replies and good counterpoints, rather than language zeal.

Let's assume that you need to write a program with a given set of requirements, and that you have a magic wand that can instantiate a high quality implementation of the program in any programming language instantaneously and for free. My hot take is that you would not want to choose Go, and you would likely want to choose Rust.

The Go implementation will have higher memory and CPU consumption due to garbage collection, while still being subject to memory bugs. The Rust implementation would be as efficient as possible on the given hardware with minimum memory/CPU, and it would be immune to memory bugs.

In my view, the biggest challenge with Rust, and where Go wins, is the relative difficulty of writing in Rust as the language is significantly more complex. With LLMs this is becoming a non-issue, and we are getting ever closer to having this magic wand (I'd argue that for smaller programs the wand already exists today). The article advocates that Go has excellent readability. I agree that Go has trivial syntax, but given that it's so verbose, I actually find it easier to read Rust code. Its higher expressivity allows you to see the higher level intention of a piece of code more easily.

Many of the other benefits the article mentions for Go are equally applicable to Rust: compiler error messages are super detailed and a great help to coding agents, auto-formatting, a great language server, and a package ecosystem.

I agree all in all.

I guess from a pure language POV, one might argue that rust leaves humans with more opportunity to add abstractions that are too clever and too hard to wrap your head around. That doesn't feel like a strong argument, though.

Then there is of course the ecosystem, where go maybe has better libraries for some stuff (while rust may have better ones for other things).

If you are going to take the human out of the loop you could just write the program in assembly or machine code directly.
