Right but hats the point im making - unless a kid is very strictly trying to actually learn a particular subject, no amount of edutainment is gonna give them any kind of professionally applicable skills.
Now if a kid watching videos that are long form treatments on specific subjects and are following allong with a pen and paper doing practice problems, sure, thats a case where youtube might give you some serious skills, but that is a tiny fraction of kids and those same kids would have been doing the same shit with textbooks at their local library. Youtube is waaaaaaaay closer to being purely a distraction than to being something we could consider "educational" in any serious sense.
