You've pulled numbers out of the air, and conflated the topics _again_. Taking your number at face value, that screen time generally includes work time, and doubles up on time (internet plus TV). It's also not an average person spending 8 hours a day as an escape. Finally, I think you're misremembering the past here, at least my experience was that people _did_ read and watch TV for the majority of their leisure time. I can't speak for a time before TV unfortunately.
Yet again, you're conflating screens and social media apps. You say screens are unhealthy (well, the modern kinds, not the kinds that you had in the 90s), but only talk about TikTok, and not youtube channels like JustinGuitar, This Old House, Serious Eats, etc etc. I don't think anyone here (and I certainly am not) is claiming that the amount of time spent on Instagram/Snapchat/TikTok is healthy (who knows, I might be eating those words in 10 years), but this fear mongering is _exactly_ the same as the video game propaganda that came out 30 years ago. Unfortunately, I'm finding google hard to wrangle today on this topic, but here's an argument from 12 years ago [0] that pretty much makes the same complaints about video games that you're making about TikTok here.
> And I have 40+ years of firsthand data ... You would have had to actually been alive before to know that.
1) You're assuming my age here. 2) Your argument boils down to the same argument that has been made by every generation for 2000 years. "Your elders know better because of experience, so trust me" _My_ experience with people who play this card play it because it's their only card. And after all, I should know, I have 30+ years of experience of people telling me that.
