The aggressive headline is a hook which is what bloggers have to do I guess, but it doesn't need to be polarizing. The argument boils down to "If you made a TUI only because making a native app is hard, then LLM's fix that for you now".
Making GUI apps has been way too hard on all platforms since forever. Frankly I think it's gotten worse for 20 years. People started fleeing to web wrappers like Electron to escape the horrors of native UI development.
So if that was the reason why you made a TUI, take heed. LLM's can chew through UI frameworks for you.
But I solidly believe TUIs are often better than GUIs even if they were equally easy to make. They liberate your app from having to follow the fracture and fashions of GUI's - Liquid glass, Windows 8, SwiftUI, WinUI3, QT, GTK or whatever. A TUI allows muscle memory that you learned on Solaris in the 90s to work fine in windows 11 in 2026.
