I don't mind CLI programs. But there are definitely some things I wouldn't want to use them for. I couldn't imagine using a non GUI CAM or CAD program and a CAM program is far superior to coding a bunch of complex G-Code by hand. CLI video editing, 3D modelling or GIS work would be a pain compared to GUI versions. There are definitely places for both. Hence why we have both. Also as a counter point switching between something like vim and Emacs is about as difficult as switching between Photoshop and gimp if not moreso.
