It's interesting to see beauty, appearance, and eating disorders called out, along with racism and bullying, but little else. Those are absolutely problems, and rabbit holes to keep out of, but I'm not sure that calling some specifics out really encompasses the whole problems, or the higher level problems that exist above the topic of content.
At a higher level, short video content has become a super refined version of americas funniest home videos and mtv. There is no narrative between videos, and it just constantly presses the dopamine button.
Then you get the split videos where you have a sensory video playing alongside someone talking.
It also doesn't talk about faux excitement. Every other youtuber that isnt Miss Rachel is yelling or screaming, and basically producing entire videos of hysterical feigning of shock, mouth agasp. That transcends nearly any topic.
It also doesnt talk about learning to navigate youtube vs being fed youtube by youtube.
It also doesnt talk about advertising, especially the organicish kind. Teaching kids that the video about a guy making pancakes with Prime is a Prime ad.
It also doesnt talk about replacing friends with celebrities.
