This aforementioned demonstration, btw, would have to become obscenely apparent to the average every day computer user who just wants to get their work done, play a Video Game, and watch Netflix, all without having to ever even know what a terminal emulator is.
That sums it all up. The average user wants a PC that just works. Terminal is a big no for the average user, and while we dont get gui ways of doing everything an average user does, it will be a big barrier. Even calamares needs to be waaaaay simpler (like a “i have no idea what im doing, configure it all for me” option).
