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.
