I think this is an interesting and cool direction for Cursor to be going in and I don't doubt something like this is the future. But I have my doubts whether it will save them in the short/medium term:

- AI is not good enough yet to abandon the traditional IDE experierence if you're doing anything non-trivial. Hard finding use cases for this right now.

- There's no moat here. There are already a dozen "Claude Code UI" OSS projects with similar basic functionality.
