I think that's a great way of describing it. Watching "educational" content feels better or more productive than watching a Let's Play, but it's all basically empty entertainment -- the medium and the algorithm sort've necessitate it. Which is definitely not to say there's not awesome resources on youtube for actually learning things, but, for the most part, I'm not watching things that actually take mental effort. I'm more often just letting trash wash over me while also convincing myself that it's OK because "I'm learning" (even though whatever trivial factoid being discussed is immediately ejected from my brain when the next video starts)
I've realized that the internet has a numbing effect on me. It all washes over me until I feel absolutely nothing and I'm just mindlessly consuming. My ISP was recently down for a day, and it actually made life (at least temporarily) more interesting. Rather than just sitting in front of a screen and having content pumped into my veins, my SO and I had to leave the house to seek out things to do.
Then the internet came back and now we're both back on the drip.
You can get highly informative, mind-changing videos with 10k-30k views. And on the other end, hot-take, "debate me bro!" Twitch personalities with 1M-3M views.
That's the nature of it, don't see this on any other category really.
