There's right and there's wrong, ask anyone and they'll probably tell you the lines are clearly drawn. But ethics evolve over time and technology is accelerating that change says Juan Enriquez. He's a cofounder and investor in companies on the cutting edge of biology and technology. He looks back at the ways our thinking about issues like slavery and gay marriage have evolved and the role technology plays in those shifts. At a time when so many are polarized over their own versions of what is right, he suggests forgiveness and humility in his new book Right/Wrong: How Technology Transforms Our Ethics.
