"I knew all these answers too, because I was a developer in the 1990s."

I think you're onto something greater. Maybe Google should hire more smart people who were developing in the 1990's as they're a nice, middle ground between ambitious, young folks and the been-there-done-that greybeards. Them realizing such people already know all the shit they're trying to teach their developers might be way to sneak older people into these tech firms. Haha.
