#or maybe he just wanted to be sure SOMEONE would run his smuppet empire once he was gone

Dont forget that considering the fact that SBAHJ appeared to have somewhat of a fanbase in universe and also alpha daves entire Deal, we can extrapolate that Dave was not only taught the basics of math and economics, but also likely some Marketing, SEO, how to maintain a brand and how to build an audience. And if you want to go with the website changing during the SBAHJ comic sections as Dave having done something with the code, probably at minimum basic html and css

Given that bro was expressly preparing dave for the game its also likely that he was trying to prepare dave for What Comes After. Unfortunately bro strider has zero emotional maturity or sincerity and is an irony poisoned megalomaniac living a permanent bachelor lifestyle away from society or all other connections with his fellow man, so there was only one way he could prepare Dave for life after a fight: having so much fucking moolah that no one gives a single damn what freak shit youre doing.

Yeah, it's hard to imagine Bro either teaching stuff to Dave or sending him to school but it's fair to assume he did at least one of those, Dave's not an alphabet, he's like too alphabet actually (there's a kid that could kill it at scrabble)

Plus he did teach him data structures and rap so there's precedent
