iPod designer says we need to track our digital lives

Tony Fadell, a former designer for Apple who's been called the "father of the iPod," said smartphones and social media have gotten so good at getting users to pursue "another dopamine hit" that tech companies must help users track their use.

Why it matters: Fadell is joining a growing chorus of big names in Silicon Valley who are warning that smartphones and social media are taking over our lives, and leading to everything from depression to the spread of fake news. The country's biggest business group will warn today of a coming "techlash" as the chorus grows.
