Now you've got eight-year-olds all over the place.

They're walking to the store to get milk.

They were doing errands.

They're outside playing.

They're walking the dog.

Now adults see eight year olds outside.

And at that point, people will stop calling the police when they see an eight or nine year old outside, which at present some people do because they think it's some horrible, dangerous anomaly.

Right, but you know, look, but this year things will be different.

This year they'll cheer you on and they'll do it themselves.

No, this is the year for collective action on all these fronts.

Sure.

So from the parents point of view, a phone is the worst because it's the most portable.

A phone is with you all the time, especially when you're outside the house.

My advice is that nobody give a smartphone before high school.

Anything you can do on a phone, you can do on an iPad.

It's just less portable.

So I would say, again, don't give your kid their own iPad that they can hold on to and customize and communicate with strangers on and watch porn.

Don't do that either until high school.

For you to have an iPad in the house, your iPad, that you give them sometimes, there's all kinds of good stuff that they can do.

And also, let me be very clear.
