Just one example of the top of my head: filter by labels, sort by name, select a few pods using ctrl+click, view logs. GUIs were super quick at this sort of stuff in the 90s. I use kubectl myself, but when I see stuff like this it really seems like people just want GUIs again.

There's two different levels to this imho, a tui is usually still a non-bloated self-contained binary that can run on windowless server envirorments just fine.

TUIs can have GUI like affordances UX/UI wise regardless of if they use the terminal as the contract or a window server/gui lib
