To respond to everyone at once -
I have experience and teachers so I'm not solely relying on these videos. I use the short videos as a fast discovery of what's out there and I'll sometimes watch long videos afterward. LLM sites also work well for this discovery and I use that sometimes but it is a bit more work from me (which sounds strange to write re: AI) because I have to type out what I want instead of relying on algorithms that use data collected about me.
I use Facebook Reels (rather thank TikTok) which show me stuff anyway after I click on a link shared by friends so having it show me things relevant to learning seems like the best option here in case I click on next video.
