You're probably right. TUIs (being old) have selection bias towards quality. However, my experience writing TUIs is that it's not even the same class of difficulty as writing GUIs. GUIs by any means have way more overhead and learning curve. Not to mention that a TUI is more likely to be immediately CLi compatible via adding a --no-tui flag, or CLI patchable via --tui.
