Obligatory fuck AI and the illeterate bros pushing it.
What kind of videos, though? A lot of such material is very far from being proper educational material that we show other people to really teach them much, let alone educate them well enough to be anywhere trustworthy. This is a very processed material, with years of preparation once you consider the prior education of the individuals involved in the creative process - think of the past experiences silently influencing them, their initial knowledge on the subject obtained from somewhat basic facts from school or otherwise, their misconceptions, iterations that nobody knows about, and many other things that we don’t usually directly associate with the act of working on something like a video, but that eventually do dictate a lot of the decisions and opinions put into it.
It’s one thing that the AI has no intelligence in it whatsoever, but the fact that it’s being pumped with information and “knowledge” in basically the reverse order doesn’t help it become any better.
On the other hand, the entire thing is not about making something that works well, but something that sells well. And then there’s people putting too much faith into the thing and trusting it with way too much stuff than they should (which is also the case with a lot of other tech, though, admittedly).
