I get their point, though. It's less about seeing the animation of the move, and more about seeing state. Seeing state you're manipulating is helpful. CLIs, being naturally line-oriented, don't give you that.

Myself, I do a lot of file management in Emacs these days. Dired - Emacs folder viewer - essentially turns output of `ls` into interactive folder listing, that you can manipulate the way you'd use an orthodox file manager like Norton Commander or Midnight Commander, but that you can also just edit as text and have Emacs apply changes to the file system. To kind of boost your point about "normal" being learnable, it's absolutely normal for me now to expect to be able to rename files or change permissions by editing output of `ls`.
