I firmly believe that a society cannot heal from the wounds of war without accountability for serious international crimes. How can a society move towards a shared future while fundamental disagreements about the past and about responsibility for past crimes persist?

AI has been an area of technology for many decades, but the advances of the past five-years show us why this is one of the major technology events of the last several centuries.

The vision for Zappos was for it to be about the very best customer service and for the Zappos brand to be synonymous with the very best customer service.

Since citizens' militias are anachronistic, gun owners now use the second amendment merely to defend individual gun ownership, as if that somehow offers protection against tyranny. A reckless, right-wing Supreme Court has agreed with them. As a result, gun ownership has become perversely linked to freedom in the vast gun-owning American sub-culture.
