"behaviour X can't propagate because it's not selfish enough" is a weird argument
humans copy behaviours(/memes) all the time without getting any obvious individual benefit
consider weird internet fads. why was the Harlem Shake copied?
"lots of people are stupid" is imho the wrong answer. i think we simply have an affinity to copying behaviours.
@grainloom well OTOH those things do give you either internet points or make your friends happy, so there's definitely "selfish" incentive to do so
@f0x but _why_
what _is_ "internet points"
_why_ do they make them happy?
@grainloom in it's purest sense they mean "i've made x people happy". Or it's just brain going ooh numbers
@f0x and that reverses the relation and gives a new question:
why did people get internet points for doing it? not when it was already popular, but when it was just the first few
@f0x ye, it's like, social acceptance / support / whatever
