And to make matters worse, unlike a GUI, the terminal doesn't provide any semantic information about the content it displays to the OS. This is a problem for accessibility software, screen readers, UI automation, voice control etc. If you want a screen reader to announce that a menu option is selected, you need some way to signal to the OS that there's a menu open, that some text is a menu option, and that the option has the "selected" state. All serious GUI frameworks let you do this (and mostly do it automatically for native controls), so does the web. TUIs do not (and currently can not) do this. While this is not really a problem for shells or simple Unix utilities, as they just output text which you can read with a screen reader just fine, it gets really annoying with complicated, terminal-based UIs. The modern AI coding agents are very prominent examples of how not to do this right.
