Only for software engineers who are already familiar with terminals. Most non tech people I know and in my company absolutely hate TUI. Even a fraction of software developers who spend most their time outside terminals (especially those that are on Windows and/or use specialized tools/IDEs) prefer to avoid TUIs as well.

Many "non-technical" folks who have interacted with virtual 3270 terminals for all sorts of mission critical tasks would disagree sharply with that assessment. And those are essentially TUIs.
