Human centered design research established long ago that GUI applications are easier to learn and easier to use. Terminals are a good 'lowest common denominator' due to their simple design and low cost implementation. People want the benefits of GUI with the portability of terminal applications which has resulted in ASCII-art boxes, menus, progress bars, trees, etc. These fancy new terminal emulators further enable these high-end-for-a-terminal-though-low-end-for-a-GUI features.
