Well if such a universe exists, there is probably one where it turns out exactly the same w/o math PhD, and another where its a very different game. In any case, we're not privy to those universe's goings on :/
To that I'd say if you had a jazillion monkeys with a jazillion typewriters, the monkey that types Dwarf Fortress has at most at 50% chance of having a PhD
That universe exists and the game is called Rimworld!
I thought it was discworld
Turtles all the way down
I would make an even stronger assertion that this is almost certainly the case. ;-)
Classic theoretical mathematician answer, but games are applied mathematics :P
