#12i have not used go for a while until claude code 4.5+, and yes it's the best language for AI coders.

#13I think the more you can shift to compile time the better when it comes to agents. Go is therefore 'ok', but the type system isn't as useful as other options. I would say Rust is quite good for just letting something churn through compiler errors until it works, and then you're unlikely to get runtime errors. I haven't tried Haskell, but I assume that's even better.
I built an agent with Go for the exact reasons laid out in the article, but did consider Rust. I would prefer it to be Rust actually. But the #1 reason I chose Go is token efficiency. My intuitive sense was that the LLM would have to spent a lot of time reasoning about lifetimes, interpreting and fixing compiler warnings, etc.
I've never actually seen it get a compiler issue arising from lifetimes, so it seems to one-shot that stuff just fine. Although my work is typically middle of the road, non-HFT trading applications, not super low-level.

#14you had me at Compile time bugs, strong typing, and static typing.
With Go it will increasingly become that one has to write the design doc carefully with constraints, for semi tech/coder folks it does make a lot of sense.
With Python, making believe is easy(seen it multiple times myself), but do you think that coding agent/LLM has to be quite malicious to put make believe logic in compile time lang compared with interpreted languages?

Exactly. Here's my experience using LLMs to produce code:
- Rust: nearly universally compiles and runs without fault.
- Python,JS: very often will run for some time and then crash
The reason I think is type safety and the richness of the compiler errors and warnings. Rust is absolutely king here.

I've built tools with both Go and Rust as LLM experiments, and it is a real advantage for Go that the test/compile cycle is much faster.
I've been successful with each, I think there's positives and negatives to both, just wanted to mention that particular one that stands out as making it relatively more pleasant to work with.

Have also wondered how Haskell would be. From my limited understanding it’s one of the few languages whose compiler enforces functional purity. I’ve always liked that idea in theory but never tried the language

#18Go's fast compile times (feedback) are good for dumb models. Smarter ones are more likely to get it right and can therefore use languages with richer type systems.
Re: A case for Go as the best language for AI agents
#19I independently came to this conclusion myself a few months ago. I don't particularly enjoy working with Go. I find it to be cumbersome and tedious to write by hand. I find the syntax to be just different enough from C++ or C# to be irritating. Don't get me started on the package versioning system.
But it does have the benefit of having a very strong "blessed way of doing things", so agents go off the rails less, and if claude is writing the code and endless "if err != nil" then the syntax bothers me less.
Re: A case for Go as the best language for AI agents
#20I happen to just stumble across this article https://felixbarbalet.com/simple-made-inevitable-the-economi... extolling the virtues of Clojure. It specifically calls out Go for not being simple in the ways that matter for LLMs.
I've no idea myself, I just thought it was interesting for comparison.
