Maybe for developers, but I can't imagine most people going back to the terminal. The smartphones won and has the largest market. It would be especially awkward to use a terminal on a touch display. Maybe with voice this will be easier, but I doubt people want to go around in public talking and giving instructions to their phone. UIs are here to stay.

I do not use terminal. Cursor is IDE. The point is not Cursor either. But AI agents with smart model like Opus 4.5, who does heavy work.
