Rust is legit one of the best languages to "vibe code" in.

The emitted AST has a lower defect rate since it incorporates strong types and in-built error handling. Other pros include native code and portability, but downside is the compile time.

This could be a subjective feeling with no real data to back it up.

People say same about Go as well that it's type system and limited feature set makes it the best AI friendly language but there too, it just seems like a hunch rather than a proven fact.

The thing is that this argument doesn't work with Go because its type system (and the whole language, really) is much less expressive and compiler gives a lot less feedback to the LLM. So it tends to have to write more unit tests and do more cycles of testing (and spend more tokens) to get it right.

The argument about type system is absurd anyway. The types in a program aren't a universal vocabulary that the LLM would already know about like the words of English language. They are unique to each program and domain so an LLM can't be better at it.

Let me elaborate further - it's like the proficiency of LLMs in writing English vs writing Sawahili or Kurdish.

The types of a program are like Swahili or Kurdish etc even worse because those languages still have sizeable chuck on the Internet and digital archives but types of a program are very specific to it.

If we are gonna go down that rabbit hole, then the natural conclusion is Haskell.

How good are LLMs at understanding Haskell errors and then dealing with them?

The last time I had a go with Haskell, the errors reminded me so much of hellish terminal compilers from the 80s and 90s that I quickly gave up. Been there, not doing that again.

Which seems pretty reasonable tbh. Claude Code is amazing with Elm in my experience.

Well those people are simply wrong. Go and Rust type systems don't even remotely compare. Go types suck.

Downside: CC and Codex will write, compile, and fix in a loop until it has a monstrosity rather than designing something smarter.

Excellent comment.

As a downside, the compile time is somewhat offset once you're using agents (and especially parallel agents) anyway. Since all of your edits cost a round-trip API call to a third party server, you can accept a slightly slower compile step.
