You've got TikTok backwards. It transforms into whatever the user is. If you use it for a while and keep following creators you like, it will eventually learn what kind of content you like. On the other hand, if you quickly scroll past the obnoxious dancing, it will fairly quickly disappear from your feed.

At this point, my TikTok is essentially electrical engineering. But it kind of keeps shifting to wherever my interests are at any given time.
