This is annoying but only needs to be solved once at the start, either by the LLM or the human guiding it. A single prompt of "Set up a uv project in this directory with Python 3.13" is enough that it's never an issue again for that repo.
> Goroutines are a far more tractable primitive for coding agents than threads, callbacks, async/await, or any of the colored-function regimes that dominate elsewhere.
I disagree with this. Goroutines, along with threads, callbacks, and traditional async, are all in the same category: spaghetti of unbounded background tasks. Structured concurrency [1] on the other hand is dramatically easier to reason about. Python has support for this (in Trio and asyncio.TaskGroup) as do other languages like Kotlin and Swift. Function colouring a red herring; if anything, it's useful because it highlights the scheduling/cancellation points in your code.

This really does read as "Go is my favourite language". In fairness, that's a good reason to choose a language to use with an LLM (so long as it's powerful enough and not too obscure). But let's not pretend it's the best language for everyone.
Any time you see anyone overly fixating on "function coloring" for any context other than ancient versions of Javascript it's a clue that the speaker has no idea what they're talking about.
Goroutines are literally threads. Yeah, this really is a "go is my fav" article.
This could be because our go code is typically smaller more defined services but I don't really believe that since even the isolated python services are pretty spaghetti looking.
The parallelism issue in particular was also not something I noticed agent struggling with in JavaScript, although JavaScript concurrency model is clearly fundamentally different.
The concurrency issues that I saw LMM‘s face was one reason why I created freelang which uses a very boring and audible concurrency model of OS processes that use the file system to talk instead of IPC, shared state, or anything like that. Higher overhead, lower throughput, but more boring and hopefully less bugs: https://github.com/DO-SAY-GO/freelang
The more assumptions I can move to compile time the better models are at dealing with emerging complexity.
I would go the other way with LLMs and I wish for liquid types and effects in Rust to make type specifications even more strict.
P.S. effects and liquid types and type specifications in general add a lot of busywork, but models have higher level of tolerance to busywork compared to developers.
The compiler is incredibly helpful because it catches errors and gives clear explanations and the LLM can iterate over it. I’ve also added the elm-review package with the default configuration, which is fantastic for ensuring code quality.
I have worked extending the Elm compiler and both Opus 4.6, GPT 5.4 and GLM 5 had no issues both with the Elm compiler (written in Haskell) and my extended Elm.
I didn't see them hallucinate much, not more than on mainstream languages.
In the last year or so, I have been using LLMs, to assist my work, with generally, excellent results.
I have noticed that the LLM delivers much better PHP, than Swift. I seldom need to rewrite or correct, the PHP code I get from it, and am constantly correcting the Swift. Part of the reason, may be that I am a much better Swift programmer, than PHP programmer, and there’s just a lot more Swift code. I haven’t really taken the time to analyze it.
I have my theories, as to why, but it’s not something I’m really into researching. I’ve just noted the trend.
And UI code quality tends to be technically pretty crummy/low-discipline. Your UI code doesn't need much consideration around data races, for example.
Hard not to think that's a major part of it. IME you make loads more corrections in languages you're more opinionated about (and opinionated usually follows more experience & confidence).
I correct AI Python all the time. When it cranks out TypeScript I just check it works.
On the other hand, even if that were true, I don’t know how important it would actually be since LLMs can generalise across languages well.
It might be best to pick languages where it’s just harder to screw up, the canonical example being to prefer typescript over JavaScript.
Or you hire a team of specialists for the language you want. Perhaps niche languages should have fine-tuned LLMs in the same way.
So I think the author is saying that go is a simple language that tends to have less solutions to the same problem. I personally agree to that to a degree.
What I don't agree on is that we can choose what "low variance" is. There is a lot of go code out there, it's shape may have little "noise", but the variance is massive.
They seem quite good at figuring this out in my experience
It would be an interesting language, had it been released at the time of any of its influences, Oberon in 1987, Limbo in 1995.
Back when the type system ideas from CLU, Standard ML, Cedar were still taking off among industrial programming languages.
That generates plenty of excitement.
It was intentionally designed for programmers with limited skill.
Go language creator Rob Pike:
> The key point here is our programmers are Googlers, they’re not researchers. They’re typically, fairly young, fresh out of school, probably learned Java, maybe learned C or C++, probably learned Python. They’re not capable of understanding a brilliant language but we want to use them to build good software. So, the language that we give them has to be easy for them to understand and easy to adopt.
What a coincidence, since Rob Pike wasn't capable of designing a brilliant language.
