>By who, and for who?

ages 0-6, increased vocabulary with increased screen time https://srcd.onlinelibrary.wiley.com/doi/10.1111/cdev.13927

> My kids (ages 5+7) watch significantly less TV than their peers (as well as currently almost zero internet access), and are frequently complimented on their command of vocabulary and ability to express themselves.

Compliments are nice I suppose, but theyre a poor metric when regarding vocabulary size.

> By amount of time that people spend on the internet, it is mostly doomscrolling and ragebait. If only we could take that part of it away.

"most" people I assume doesnt include you? Youre too smart to fall for it, obviously.

Have you read the paper you linked? It indicates at best a slightly positive outcome on average, with many caveats (video is worse, the younger the kid the worse the effect, removing educational content results in a negative correlation, etc). It also links to another metastudy that covers a larger age range, and indicates a negative correlation.

I'm talking about school reports, among other things.

It's something I struggle with daily, and have put a lot of thought into what I want from my use of online technology. Eg, I don't have a smartphone. How can a kid be expected to make good choices if I can't?
