Technology: your master, or your friend? Do you feel ruled by your smartphone and enslaved by your email or social-network activities? Digital technology is making us miserable, say bestselling authors and former tech executives Vivek Wadhwa and Alex Salkever. We’ve become a tribe of tech addicts—and it’s not entirely our fault. Michael talks with Vivek Wadhwa, co-author of "Your Happiness Was Hacked: Why Tech Is Winning the Battle to Control Your Brain--and How to Fight Back." In the book, learn how we can reclaim our lives without dismissing technology by how to avoid getting hooked on tech and how to define and control the roles that tech is playing and could play in our lives.
