It's not about learning (anymore). It's about consuming content. People spending (wasting) their time on X and YT are not there to learn something but to get their social media (dopamine) fix.
I hate YT, X, Insta. Don't even have an account. Some years ago there was really great content on YT, now it's mostly clickbait.
There's still lots of great YT content, much of it by the same producers you allude to, and they need your support more than ever with all the slop around them.
