But you have exactly the same fonts in your terminal and modern terminal support variable fonts and all those bells and whistles.

They can even show images these days.

Some of the elements can't be recreated 1 to 1 ofc, like borders with delicate margin\padding adjustment, but this is about it I think.

To each his own, yeah. From my experiment GUIs tend to overcomplicate things and display too much info you didn't need in the first place.
