Then, the algorithm starts building a perfect feed just for you. Funny videos, drama, motivation, memes. Your brain keeps getting tiny dopamine hits, so you keep [music] scrolling. That's why TikTok feels impossible to stop watching. It's not a random. It's one of the smartest recommendation systems [music] ever built.
