What would happen if forty-five-year olds like me took over Quora?
You’d get some geniuses like me, and some dumbasses like, oh, I dunno, whoever your least favourite middle-aged Quoran is.
Ditto teenagers. There’s plenty of dumb answers from the middle-aged, and plenty of genius answers from teenagers.
OK, there would be more dumb questions and dumb answers and herp derp nonsense attempted on Quora. Not because teenagers are dumber than the middle-aged, but because they lack the impulse control. I’ll concede that.
So the proportions would be different, and would need even more policing. Which, regrettably, would probably end up meaning even more QuoraBots let loose to chop people’s heads of. But it would be a matter of scale, not an absolute difference.
