alt Hacker NewsIt sounds like you completely missed the point I was making: that actually implementing such a highly dynamic TUI application normally requires a significant amount of state tracking and it is significantly easier to write such apps using a functional, descriptive UI framework instead of something like ncurses.
Take it from someone who, in those 24 years, has written UIs in jquery, react and ncurses (and yeah I've tried out Ink and it's great).
"all the downsides that come with that" yeah well, while you're stuck implementing your app in the Best Possible Library, millions of people are happy using claude code and it's crazy useful.

CC is not even that complex of a TUI. It’s certainly not as complex as many of the GUI programs I use daily. And yet it’s by far the buggiest and worst performing. I don’t understand the desire to make excuses for this. The reason people use it is because it’s the only way they can afford to use Opus and Fable. If Anthropic let people use their subs with other harnesses their market share would plummet.
If they could migrate an entire runtime to Rust why can’t they migrate CC? It’s not as if React is the only way to do declarative UI.
There are fantastic TUI frameworks for Rust, like Ratatui[0] (there are a lot more options, this is an example). You can write beautiful TUIs in native languages, without ncurses or C or C++.
Go has such frameworks, same with C# (which you can AOT compile) and so on. You're not stuck between javascript and C.
