Not as fun to write as Python and Nim, but I don't have to write it.
And I expect that it will turn out Python is the most productive. As it is most easy to reason about. It allows for the most elegant expression of the idea behind a program.
The first tests I have seen seem to confirm this. One recent example:
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.
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.
This sounds like your personal feelings, not quantification.
If a language is simple, it' easier to generate good code.
Prefer standard Go libraries and tools.
80% of the time I can get by without external dependencies (outside of Go's X repository)
I still think Go is a very excellent choice but I have switched to, of all things, AssemblyScript within a Rust host. I've been very happy with it - surprisingly so. Compile time is a major drawback of course.
I never seen k8s cluster that doesn't have some go process that segfaults once in a while because someone forgot to check `err`.
Only good thing got going for it is its vulnerability scanner. Which will be working overtime with all that "AI-assisted software engineering"
I think the most important thing is how big the standard library is. Pulling in 3rd party dependencies is where I begin to lose a lot of faith with LLM authored code.
As a lead I'd love to use rust, I will put in the time on my own, my team won't or can't. They treat this like any other job they signed up to deliver value with what they know. For hiring not everyone has the talent pool and fund access to get the goat-ed engineers that congregate to tech hubs for maximizing their income. Then if you get through that cherry on top is LLM's are only as smart as you guide it to be. There is probably a staggering amount of ways to write 1 approach to business logic, you may not know the ideal pattern so you'll commit to a worse one on the company dollar.
I'm moving my team's projects slowly to go because, its easy to go from novice to advanced in terms of code writing,legibility and patterns. We also don't have deep ecosystem requirements to ts/python in most of our work. It is verbose but I don't mind that on token spend if it gets done with with validation/error handling which it obnoxiously enforces. It runs cheap, ecosystem is good for platform eng, standard library does a ton out of box.
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 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).
Of course it can’t just be simplicity, it has to be “opinionated” simplicity. Rolls eyes.
Google.
Now one can say that a programming language and its design or usefulness is - or should be - decoupled from the company developing is. I am not opposed to this, in theory, but Google goes way too much on my nerves these days. And I am hardly the only one here.
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.
If you're going to have an agent write most of your code readability is very important.
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.
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.
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.
I my self and teams members are slowly reading less code and requiring agents to prove things work the way we want in other ways.
The default sentiment is humans should read code it's more progressive and a leap of faith to start giving that up.
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.
Rust is definitely jarring to look at, in the same way that decoding some strange C declaration can be, in ye olde days when you had to float all this context in your mind while doing work. But with modern tooling who cares: "explain this lifetime to me"
You can pretty clearly see the limitations if you read, for example, the type of code the Protobuf compiler generates when trying to compile Protobuf/gRPC enums or structs into the way-more-limited Golang type system (this is despite the two being designed to work together). And it could really do with algerbraic data types and other modern programming language features.
Also the type system does have a couple weird behaviors that seem straight out of JavaScript. Like the difference between struct and interface nil for example:
```
var buf *bytes.Buffer = nil
var out io.Writer = buf // now out is nil
if out != nil {
// This block will execute because out is not nil
out.Write([]byte("crash")) // This line will crash because out is nil
```
Many things about the language almost seem to be designed to simplify the implementation of the compiler rather than to benefit the developer experience.
Go is simple, no “magic” marcos or meta programming even with just a little programming in any language it’s not hard to understand what the go code is doing.
No way to know until someone does the science on this. Until then it's just people saying that more static checking is better. But I do think, anecdotally, python is horrible for LLMs.
I use LLM daily to write code for and "with" me, I also write code without LLM. Most people I come across mix it up. A few do it all by hand, and equally few all by LLM I would say. Is that just in my corner of the world?
My entire company for example does not write a line of code. We manage agents and that's it. Many, many, many companies and people are already doing this.
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.
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.

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.
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.
I agree very strongly. There's no debate about things that have 1000000 permutations in other languages. e.g. The correct format can always be checked by `go fmt` with no real config options. the end.
though the letdown with Java is the wider ecosystem that makes unwarranted contraptions out of simple things.
I've found a lot of success pointing claude at locally downloaded docs over llms.txt URLs but not sure how to scale the pattern for a bigger project.
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
I didn't say that. :)
> where do the results claiming that AI agents generate superior Go code actually come from?
Like I said - reports from users.
> Is it a fair, apples-to-apples comparison?
No - these are reports from users, not a systematic analysis.
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.
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.
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.
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.
"After 7 years in production, Scarf has reluctantly moved away from Haskell"
And moved to Python, pretty much for the reasons you stated
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.
| 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.
Is Go better than CSS if you are doing web layouts? Is it better than zig if you are outputting minimal wasm deliverables? Is it better than swift if you are doing iOS specific development? Is it better than bash for OS scripting?
Think about what you are doing and choose appropriately. This was true before LLMs.
Are you having fun? Chose LISP then
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, ...)

- 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).
- 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.
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.

Joking aside, as much as Go's stdlib and tools do the heavy lifting here, Go's verbostiy and expressing simple things in lots of lines worked against me most of the time.
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.
> Gophers often speak of how they love that they can never tell who on their team wrote a particular piece of code—it all looks the same.
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.
Pichai wants to eliminate engineers, and DeepMind wasn't fast enough or too noble for it. Now people need to be propagandized for their obsolescence.
Stuff like like which compilation targets are available, or which has the most mature library for what you're doing, or maybe you're integrating with something that anchors you to a specific interface type.
Anchor your language choice to the problem you're trying to solve and the people you're trying to solve it for.
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.
Might be a skill issue, but I got frustrated with it on new projects constantly.
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 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.
Sounds like you made a decision right there. The rest is just retro-justification, not a logical argument or comparative between options. It works for you, good.
I guess if you consider enough attributes or "dimensions" then any programming languages will be the furthest in some direction, including Go.
Listing particular sets of preferences for which Go is not optimal is not sufficient unless you can show the list to be exhaustive.
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 similar to popular languages like C, JS/TS, & Python. And so, easy to get started.
> highly value a type system that catches errors
Probably these folks already use even less popular ML-style languages like OCaml & Haskell; or (comparatively) obscure ones like Agda, Idris, & rocq/Coq.
The article specifically discusses how Go is well-suited for LLMs. It's not going on about general programming topics.
what would be the purpose then?
Go is behind, specifically, you have no guarantees that a given machine has Go installed, and doing stuff like gluing commands together, inspecting some files, pipe output around, or automate the boring thing in 30 seconds.
Sure Go beats bash or sh when the thing you are doing starts to become real software, but that is a problem that sits between the chair and the keyboard.
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.
People who want to use the most appropriate tool.
> Use the ones more appropriate for what you are trying to do.
What they are trying to do is find a programming language that LLMs work well with.
> So you are using Go with LLMs for the objective and destination of token consumption for token consumption sake?
The trolling gets more intense with each comment ...
P.S. Someone else responded:
> But this isn't a user story. The user story is what you should be picking the tool for.
I don't see how this is at all relevant to my comments. I'm certainly not going to argue about what some other party should or should not be doing.
But this isn't a user story. The user story is what you should be picking the tool for.
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.
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.
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.
Citation absolutely needed.
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.
Each have their trade-offs, both can support native compiled application code. Some architectures are easier to review and code in golang, but others go much better with Javas richer ecosystem and better composability.
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.

Poor defaults break systems by a thousand cuts. They seem to make sense when designing the language (more convenient, less typing, etc), but then they very quickly become liabilities as project complexity increases. Go made the mistakes of mutable-by-default and silent-error-dropping, but their cyclical-import-forbidding was a good call.
A couple more comments like this from you, and I'll be able to say, "cyanmoonx has a history of blaming the talent rather than bad tools". There being a history like that is neither an argument for nor against tools being bad. And also, don't forget that bad tools and bad talent don't rule each other out.
There are language implementations that would have been more minimal than that, sure, but there was no obvious way to get LLMs into alignment. I tried. Multiple times. When I switched to Go, it just worked. It may not be technical perfection, but it let me ship something I had almost given up on and it has satisfied users. The tradeoff was worthwhile for my needs. That tradeoff may not be acceptable in all cases. Hence what is best being meaningless without at least defining which tradeoffs you are willing to accept.
Two things to keep in mind here:
1. TinyGo is not Go, more Go-like or adjacent
2. 10KB still matters a lot in a lot of minimal target/usage scenarios
> ...And so many languages have an opinionated formatter these days
The crux of GPs post is for Go, there is no debate as 'go fmt' is the only one that matters. Black is great, but some people prefer Ruff, leading to ...debates about which formatter the team/org should use. Go's batteries-included philosophy makes those discussions moot on so many levels beyond formating.
Similar to black but faster, written in Rust, by the same team who created uv.

I call this the Go paradox.
I simultaneously believe we should reach for it 80% of the time to solve common collaborative problems. And being a poorer language is actually an asset in these cases.
However, in doing so, we get rusty lose our fluency in more expressive, perhaps even better languages.
How does that work? Are they generating the same project in different languages and comparing the results? What does it mean for the code to be "better"?
It's anecdata and maybe, MAYBE, a spreadsheet. Or a Google Form somewhere.
Token use didn't seem to be a criteria from my casual reading, but maybe you can illuminate me what section pointed to that, I may have been too superficial in my reading
Are you saying that this implementation is wrong?
"This Raft library is stable and feature complete. As of 2016, it is the most widely used Raft library in production, serving tens of thousands clusters each day. It powers distributed systems such as etcd, Kubernetes, Docker Swarm, Cloud Foundry Diego, CockroachDB, TiDB, Project Calico, Flannel, Hyperledger and more."
One of the most popular distributed DB is Cockroach which is written in go and also uses Raft: https://github.com/cockroachdb/cockroach/tree/master/pkg/raf...
You may be interested in knowing that the largest managed Kubernetes service in the world (AWS EKS) ripped out etcd for in favor of their homegrown consensus service for large scale EKS clusters: https://aws.amazon.com/blogs/containers/under-the-hood-amazo...
goBGP is arguably even worse.
I don't have a third place in mind that's even worth mentioning relative to these two.

I'm v confused by this thread
That is literally what the comment says.
The antithesis author states:
"we’ve found bugs in every Raft implementation we’ve tested, including HashiCorp Raft, Aeron Cluster, OpenRaft, and MicroRaft"> Go still has not yielded a correct implementation of Raft or Paxos while there are dozens in Java, C++, and Rust.
That says that there are correct (i.e., bug-free) implementations in those languages. The GP noted
> "we’ve found bugs in every Raft implementation we’ve tested, ..."
which says that there aren't any correct ones. You then wrote
> I didn't say other languages don't have buggy Raft/Paxos implementations
which is a strawman. The issue is whether there are correct implementations. That there are buggy ones is irrelevant.
(FWIW I have no dog in this fight ... I'm just reading here.)
But good god, the second it gets to anything concurrency-related, it just loses its mind. As much as it's gotten vaguely ok to try to let the agents loose on some bits of the codebase, they simply can't even do table stakes stuff with the kinds of concurrency you see in real life.
Zig is also good at this but requires more up front design (thread-per-core, static allocation, etc.) and consistent checks to verify rules are followed.
Edit:

That's what it says.

You claimed that, and it's being disputed.

This has veered into bad faith ... I won't comment further.

What are they implying by citing that? That every language has a Raft implementation with bugs? Yes that's probably accurate because lots of people make Raft implementations for fun and learning. Again, Go does not have a single Raft/Paxos implementation that is rock solid. I have seen many in C++, Java, and Rust that are doing tens of millions of requests per second in production for over a decade.
Is their point that Go is not the only language with this problem? My post already points out the track record is that Go is the problem for writing correct code in highly critical domains.
