There's a broader question of "why would I want to consume any sensory input? Why would I want to read a book, watch a movie, look at a sunset, have a conversation?" I can't help you there, consult your local philosopher.

But if you do want to consume sensory input, what I find TikTok excels at is: * Dances / skits * Musical collaborations (esp. The Wellerman) * Funny little videos like with a kitten or puppy * Recipes / cooking techniques
