This basically gives you the tools to develop video memes. You'll often see a video or audio clip go viral and then see a bunch of different riffs on it that evolve over time, each a twist on the previous iteration, in exactly the same way you see image/text based memes evolve over time, get mixed together, adapted for a current news story, etc etc.
This sort of thing doesn't work quite as well on platforms like YouTube, the barrier to creation is too high.
Another component of the innovation is to mix lowering that barrier with a strong algorithm to surface the best content, since you now have so much of it.
Though I wonder if there's any educational/ productive content on TikTok. This was someones argument about the difference between Twitter and TikTok: TikTok doesn't allow conversations/ debate.
Tiktok is basically set up for remixing. You can splice your reaction, or add your dub, or lip sync, or more, and any of those would take less than 5 clicks to upload.
