That's a good question. On the individual level, you can have your kids read, be creative (without tech) and give them mandatory outside time without actually demanding. (Trick them into thinking they want it) You can minimize the amount of time they're around technology. However, it's so deeply ingrained in society, there will be times where they will need to understand how devices work and how to use them professionally.

The only thing to do really is to make them understand the effects it has on their brains and the emotional responses it will trigger in the future... and come up with a way to help them balance the two worlds effectively and hope that they can help others.

Explain why it's bad and explain what it can be good for and emphasize that there's ways to not overindulge.

I think it's called persuaded discipline (lol) but yeah... basically.
