Oprah Winfrey

So what's your most important message now you want parents and educators to know?

And I know you have two school-aged daughters, and what's your biggest concern for them in this moment?

Dr. Liebke, I know you're also involved with Hugh and Sophie's organization.

What's your take on screens in schools?

Do you feel it's getting easier to get this message out because more and more parents have become equally as frustrated as you and Hugh?

I hope that it is a beginning of something that really lends itself to allowing other people to understand that we're in trouble.

We're in trouble.

Thank you for being the voice for that.

Thank you, Sophie.

Very much for having me.

Thank you for joining us.

You know, I learned from reading Dopamine Nation that just about anybody can be powerless against these digital forces that we're all up against.

The interesting thing is we regulate cigarettes and we regulate alcohol.

And there is some regulation to gambling for children.

Australia is now putting an age limit on social media.

So why don't we...

put guardrails around this?

Why aren't we aware that this is happening to our kids?

So your final word, what's the most important advice for parents or families grappling with tech addiction?

I go back to what you said in the very beginning, to understanding that this is a drug.
