Idk why the author thinks that C would be a better language than Rust for vibe coding. Intuitively, I would have thought that the more formal constraints the system imposes, the better for vibe coding (since the more powerful static checks make it harder to write incorrect code).

Of course in practice I think the author is actually correct - LLM's struggle more than humans with sophisticated formal constraints and less than humans with remembering to write a bunch of boilerplate. But I think it's a pretty counterintuitive result and I'd love to have seen more discussion of it.
