I use the TUI for a lot of agentic stuff that is not necessarily coding, from performing some cloud management commands or just dumb things like "where the hell did I alias vim to nvim?". For those things, having to reach out to the IDE is annoying.

And the way I see the future of coding is that should should be able to code from anywhere, mobile, web, your computer. You already have your code on the cloud (most of the time). Neither TUI or IDE works well currently for that.
