>I just posted a talk by Seymour Papert from 1991 where he said that kids were on computers or Nintendo for 6 hours at a time, which surprised me that even then they were "addictive." He notes that poetry, music, Shakespeare aren't "addictive" in the same way.

He doesn't make any claim as to the addictiveness of poetry, music, or Shakespeare: he pointed out that we use different language to describe childhood compulsions for one activity than we do for another.

My own anecdotal experience on the topic is that I was such a voracious reader as a child that it was a problem in much the same way I see people today complain about kids in screens. I'd hide personal books behind textbooks while I ignored classes, hide under the covers with a flashlight to stay up all night reading, the works.

My wife was like this. Her teachers came to her mother with concerns that she was reading too much.
