If the Linux command line is state of the art, then the art hasn't advanced that far. Too much of it is frozen in time, with constraints from PDP-11s with two-tone 80-char displays, and insane, arcane UI that made sense to the wizards of that day, but less so to we mere mortals. Lots of inertia there.

Still CMD is worse, and Powershell is different, but maybe not any better...
