> I think kids naturally want to fiddle with things and learn something new.
I have two kids. I can tell you that it's not necessarily true, and kids spend an ungodly amount of time silently comparing themselves to their peers. It's always "My friend has this", "My friend does that". It takes a special kind of kid to have the patience, attention and time needed to want to fiddle around with a computer. I've tinkered with computers, smartphones, etc, all my life and shared as much as I could about it with my children - they have zero interest.
Of course, they don't know about the data collection and they're growing up in a world that normalizes that kind of behavior. When looking back, they'll go-- well as a kid I had that, so I guess that's ok. Google, Facebook, Microsoft, et. al. wants that- they know it's just a matter of time.
My kids have had cell phones since 12 for 'necessary' purposes, but they were not allowed to use it except for that. Otherwise, kept in the public space, in view and must ask to use it. My oldest is halfway till 17 and hardly uses their phone now. I have been thanked for this because they notice how their friends are addicted. The goal here is to avoid priming your kids' brain to be addicted to phones, not necessarily avoiding tech.
