In 1980, Rogue for Unix was a dungeon crawl game that coincidentally used the same keys as vi for navigation. Even today, Nethack and vim are widely revered. Nethack takes vi training further: there are several two-key commands, and some prefix keys which open a "command-line" interface.

Even today, I posit that twitch video games train future developers and users on UX/UI features. In a mobile or web GUI, there are moving targets; there is progressive rendering; there are ephemeral dialogs. If you've played DOOM and Fortnite, then you're better equipped for all that.
