Is there no one who feels that kids shouldn’t have iPhones until they are 18 and don’t accidentally put information online that leads predators to them?
As someone who was on the internet by age 12 and was coding by 15 I see this argument and can't help but shake my head.
If you want your kids to grow up with zero street smarts or ability to distinguish threats then sure. By all means keep them locked in their bedrooms till 18 too.
Don't be surprised when they stop talking to you by age 21.
