I’ve had good success with Claude building snappy TUIs in Rust with Ratatui.
It’s not obvious to me that there’d be any benefit of using TypeScript and React instead, especially none that makes up for the huge downsides compared to Rust in a terminal environment.
Seems to me the problem is more likely the skills of the engineers, not Claude’s capabilities.
We would all be enlightened if you grounded this blind belief of yours and told us why these design decisions make sense, rather than appealing to authority or power or whatever this is…
It's a popular myth, but not really true anymore with the latest and greatest. I'm currently using both Claude and Codex to work on a Haskell codebase, and it works wonderfully. More so than JS actually, since the type system provides extensive guardrails (you can get types with TS, but it's not sound, and it's very easy to write code that violates type constraints at runtime without even deliberately trying to do so).
