They are GUIs --- just minecraft GUIs. One day, we will rediscover why GUI toolkits exist. The only real advantage TUIs have over GUIs is easy remoting, TBH. Maybe that's enough for people. Otherwise? They're just hair shirts.

I've use Claude to make myself a number of little tools and weird apps that only I would want lately. They need to be cross-platform between Linux and Mac and sometimes Windows. The best approaches I've found are Tauri (+Svelte for making layout easier) for lightweight GUIs but for anything more complex I prefer a TUI. The Ratatui framework works very well. A TUI feels like a "real" app as opposed to a glorified webpage. For actually serious software I'd want a native GUI on each platform.
