Earlier quoted context omitted.
My SO has TikTok. It seems like mostly staged videos and folks with barely informed political rants to me.
TikTok shows you precisely what you want to see, whether it's simple and funny staged videos or something more intellectually engaging.
It's disappointing to see folks in hacker news regurgitate TikTok marketing material as fact credulously. No service could show you precisely what you want to see. TikTok does it's best - but e.g. if I want to see no staged video, TikTok can't enforce this, because TikTok doesn't know.
