Some TUIs even have mouse (optional) support.
vim has that, and it drives me nuts. i use the mouse to select text in a terminal to copy it elsewhere outside of the terminal, but when vim is running that doesn't work, and i end up disabling mouse support every time because of that.
I guess you could argue that with the recent-ish rise of new CLI-friendly languages and frameworks like Go, Rust and Node that the people are reinventing the wheel in terms of terminal based tooling. However there has always been a strong undercurrent of people favouring the terminal for most types of work (myself included).
