The thing to understand is your last paragraph: everything big ads does is unsurprisingly focused toward making people into worse versions of themselves. You wouldn't let kids go to a casino or porn site for educational material. Don't let them use youtube either.

It could be that someone happened to post educational videos to the porn site. If so you'd might as well download them while you have the chance, but don't mistake their existence for some indication that that's what the site is for. They're still less than 0.1% of the videos, and you'd need to specifically search for them or be linked to them to find them. Assume you'll need to look elsewhere for educational material. e.g. there are 10s of thousands of results for videos for "Holocaust" on worldcat.

There's extensions to remove or hide recommendations. Problem solved.

YouTube has too much information to just ignore for education. It's the most efficient method of learning for many topics and for many people.

It's closer to PBS than a porn site imo. (The idea of a porn site with YouTube's puritan guidelines sounds pretty funny.)

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.

You can get literal pbs at pbs.org for $5/month, or your local library for free.

The problem is that YouTube and Google on a whole actively encourage the use of YouTube in schools, home schooling, and education in general. Google workspace for education is free for educational institutions. They also have a curated YouTube kids app with a giant feed of brain rot that they consider to be safe for kids, but only because the content doesn’t show anything graphic or have bad language.

On the other hand, porn services are (generally) actively blocked in educational institutions, so the content, regardless of its educational quality will never be suggested to kids because they are not a target audience. (Not to mention the legal trouble these services would have from actively enticing minors) I doubt we’ll see “PornHub for kids” our RedTube signing a contract with Blippi or Miss Rachel.

Half their business is propaganda (the other half being surveillance); of course they represent themselves as something positive. Recognize them for what they are. Point it out to others. Advocate for banning them in schools. Warn parents that youtube kids is not appropriate for children. They do near zero curation. They don't commission creation of educational content. They are nothing like PBS (as another commenter compared them to). More generally, ads are not child appropriate. These platforms have some useful content, but on the whole they undermine teaching virtues, and in fact their entire purpose is to push the opposite.

I agree 100%, and in another comment I also suggested an alternative to child protection laws, namely that we should severely restrict the viability of the ad tech business model altogether. While it does make certain niche content creation financially viable which otherwise wouldn't, in the grand scheme of things the negative externalities outweigh the good.
