alt Hacker NewsProbably 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).

How would you compare it to C#? Stable-ish There's a lot of documentation and plenty of stablished patterns, so LLM can produce it no sweat Everything and the Kitchen Sink Performant, and safeish, even if not null safe
SwiftUI has nothing to do with Swift… It’s just a UI framework that happens to have been written for Swift.
I wouldn't call Go's type system "good". It's basic or less. It's sound, at least (in the presence of data races), but that is the case (or mostly the case) for most programming languages.
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.
