Presumably you also like that they are explaining things right? I mean that seems like the more critical step. Otherwise if it's just Marquise Brownlee, you could just watch Marquise Brownlee say the same sequence of random words for 3 minutes a few times per day.
I feel I need to explain beyond just a whine.
I think this is exactly the opposite of what AI should be used for. It is going to make people dumb.
Watching a video instead of engaging your own brain makes you feel like you learned something without actually trying and I would bet it works much less well.
If someone is there adding something beyond what is already there - ie someone like Maruqise. Then it makes sense for them to be there.
If not it is just brain rot.
People already have issues with concentration. Allowing them to further allow that muscle to atrophy will not be good.
