> The financial incentives to create addictive digital content would instantly disappear
No they wouldn't.. the business model would change. Facebook sells ads to businesses and entertainment to consumers. People still want to be entertained.
What about the positive effects from advertising? Many products which I never knew existed have gone on to improve my life.
To kill addictive digital content (especially those targeted at young people), just go after them directly. I agree the world will be a better place once we don't spend 10-16 years old online. But the advertising argument doesn't make any sense to me.
