Are they?

As far as I'm aware, there are only categories of people when it comes to "the invention of the GUI":

1. People who know it was a long and involved development process involving many people starting in the 1960s.

2. People who don't care.

edit: Lol y'all some bitches.

Apple didn't "invent" the GUI and Columbus didn't discover America, but they popularized it, at least among a certain set.

No one was popularized RISC-V yet. Maybe Asus will be the one!
