There are plenty of terrible books and trash novels. Easily 99% of books are junk (often junk dressed up as non-junk). I think it's very possible that in 2024, YouTube is net more educational than reading. (Speaking in terms of total amount of knowledge acquisition.)

Maybe but YT recommendations are good enough so that you don't see those 99% you are not interested in.

Trusting an algorithm that wants you to watch the next video for ad impressions may not be the unbiased metric you think it is.

So, you always go to the library for every problem you have where you need a detailed guide?
