Now, screen time is implied to be negative. As it should be. Your average kid's screen time is not sitting at a terminal trying to puzzle out how to make a computer work. They are not sitting watching 8 hours of programming videos, or math videos, or Carl Sagan's cosmos. They aren't listening to audiobooks of war and peace. They are, quite literally, melting their brain with the videographic equivalent of cocaine. I am of the opinion parents these days who allow their kids unrestricted time on TikTok/Facebook/Youtube/etc are doing them a major developmental disservice. The entire social media machine is powered by designed-in-a-laboratory techniques to keep you locked in. If an adult, with all their life experience, cannot resist such temptations expecting a child to do the same is non-sensical. It's gotten far too easy to not only use a computer, but to become hopelessly addicted to content farms via the "always-on" new world. Kids just aren't being kids anymore.
Times were different back then. Some people may disagree, but the "nerd" kids 30 years ago were smarter, faster, and better than such kids today. No different than our grandparents having to be the same way back when. They had to be. Now, things are easier. For better or worse. The same technology that could've raised the new generation to be even better than us was instead co-opted by advertisers to hopelessly addict children and adults to what amounts to just a different form of pornography (which, coincidentally was ALSO harder for us to get...I digress). I guess this is more of a thesis on the state of the world than just computers...it's all related.
