Yes, regardless of the motivation/the author pimping his product, fundamentally he's right about the maddening nature of command input. It's terrible. Tab completion is a half-designed solution, and not exactly portable across shells. Terminals need to stop pretending they are dumb 8" CRTs from the 1970s. Virtually all interactive terminal input is through GUI applications at some point, and if it's not, it's not by choice. And performing stdin input in scripts for programs that need it? Don't get me started, and don't say "expect" with a straight face. The fact that scripting languages have no provisions after 40-50 years is nuts.
