Brad led Microsoft's legal defense against David Boies and the U.S. government a generation ago. You might have heard of that infamous antitrust case against Microsoft. Today he's fighting for Microsoft's right to shield certain customer data in the cloud.

Brad and I did a panel together at the Aspen Ideas Festival in Colorado recently about the global threat from hackers. After that we sat down and pushed record, and had a conversation for Fortt Knox.

Three things you're going to hear from Brad Smith: How his upbringing shaped his view of the world, how as a young lawyer he used technology to advance his career, and how to learn from massive upheaval – like the government's antitrust case against Microsoft 20 years ago – which I think it's fair to say changed Microsoft, the tech industry, and Brad Smith's career, forever.

That's where the title of this episode comes from: If you change the world, you change the law. Two decades later, Brad has a take on the Microsoft case that I just find profound: And perhaps a near-prophetic warning to today's other world-changers, including Amazon, Facebook, Apple and Google – and advice you and I can apply, too.
