I don't know, I have too many tools that would really benefit from using GUI (e.g. coding agents, process monitors) but are using TUI and are written in TS instead. Everything about TUI screams jank to me, even the old kind. Both internals and presentation. It's less readable, way more limited, just about everything in it is bad, maybe except the ability to mix it with the CLI programs, but it's quite niche and you could do it the other way in the GUI (embed a terminal, like many apps like Zed or Total Commander do). And of course there's absolutely nothing that stops anyone from developing information-dense, keyboard-driven, and snappy GUI apps that run headless.
