Isn't this still confined to what a terminal gives you right now (as it is using current terminal specifications)? While certainly colorful and fancy, it doesn't really introduce new concepts, does it?

I mean, for starters:

   -> unix introduced text as a universal interface
   -> bash made reusing stuff a lot easier via file descriptors, etc. (think: <(input to regard as file))
   -> powershell allowed for object oriented scripting
   -> some older systems (name forgotten/unknown) even had interactivity in the cli: click on parts of command-output and stuff happens, even after other commands have been run already
