I pretty much agree with this.

We were able to go back to one TV in the house (at least I was), and even avoid a big chunk of the ads when watching TV (by paying for Netflix/etc) and even radio (Spotify/etc).

Except we now we put a garbage TV in every hand.

It's a terrible idea because it's a tiny screen; because it's not a shared experience, but an isolating one; because it's been proven that it's bad for eyesight/myopia. But most of all, it's terrible because the content is crap.

Spending hours watching a never ending sequence of low effort 2min videos that need to deliver on the first 30s (or they're skipped) is not the way to make anyone smarter/saner.
