Personal anecdote here, so grain of salt.

But I was born in the mid90s. My dad is a tech geek, so we had a personal computer with Windows 95 and I was playing Adiboo on it at 2-3 years old. Also had a Gameboy with Pokemon. Played CS/HL/DOD in the early 2000s. All before we were going to the computer lab at my school.

So I’ve been entrenched in computers and tech my whole life. So I don’t think screen time itself is bad, but we also did not have tech in the classroom (except for the old school throw projectors).

So it probably doesn’t help that the classroom nowadays is all tech while also the kid’s home is all tech. It’s a balancing act.
