Problem is still not solved because search also returns a lot of garbage, and you don't want kids to be on a site that's 99% garbage. Xvideos could have a large library of science and history videos while still being 99% porn. Like I said, adults should download and curate the good stuff but recognize they're still in the seedy part of town, shouldn't let kids go there, and shouldn't expect it to be a platform for learning. That's just not its purpose. In fact youtube's purpose is basically the opposite of personal growth.
