TikTok is incredible, in my opinion, it really is the best content-delivery platform... but that is actually quite dangerous because what people want to see is not necessarily what they should see. It's important for people to have broad perspectives and I don't think TikTok addresses that so appropriately.
When people out of mere curiosity watch something biased/misrepresented/discriminatory/extreme and interact with that content, irrespective of whether all their opinions at that moment of time are the same as that of the content they watched, the algorithm will aggressively push similar content onto you, and there will definitely be a few who fall into "the doom".
It seems like mostly staged videos and folks with barely informed political rants to me.
That is why TikTok is more popular than platforms that only focus on engagement, because those platforms will show content that you will engage with even if it's in frustration.
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.
