The solution is parenting, period. Do not give your kid an Internet-connected device before they are ready for it.

Surely we know by now that this is not enough?

Kids find ways around everything. Even adults find the 'digital wellbeing' tools on Android and iOS useless. Just look at the multitude of apps available for digital self regulation these days (ScreenZen, Freedom, BlockSite, etc). No single solution works for everybody at the moment.

Regulation by itself is also insufficient. But maybe combining regulation with parental controls plus other measures will be effective. A 'defense in depth' or swiss cheese strategy, with multiple layers of protection.

I do hope we figure out what layers are needed soon, though. It feels like we're running out of time.

Simpler still, a “minor” bit on the phone, set by parents once. All services must respect the bit in http headers, and app stores should refuse to install certain apps. No need for id check

I imagine that many parent don’t want micromanage their kids apps, this takes care of the problem.

I’m in favor of this, but it doesn’t solve the full problem. If all your friends use social media as the fabric of their social interactions, you’ll be ostracized if you opt out as an individual.

IOW its a coordination problem. You need most of the other parents in your social group to also implement those controls.

The government shouldn't be parenting other parents kids
