So you're saying a highly motivated individual with an access to World Wide Web and physical textbooks can't teach him/herself to optimize "Twitch's video codec" or any low-level problems on their own ?
But that's not addiction! That's just managing time so kids can do a lot of [other] things. The problem with Fortnite and many games is this is where they have their social life. And they meet with friends and they play with friends. They hang out and are creative. It's not like they're mindlessly shooting, they do a lot of other things.
This statement just sounds very wrong. Why are they glorifying virtual platforms as a common social gathering ? Having tried the game myself, I don't see anything creative with it - building scientifically impossible structures to jump/hide from enemies to begin with. Alas, it's indeed "mindless shooting" and showing off expensive in-game virtual purchases.
