My attitude toward graduate students was different, I must say. I used graduate students as colleagues: I gave them the best problems to work on, and I encouraged them.

For my own personal growth I had to set out on my own.

I travel to a lot of schools, and I see firsthand that while we do still have a lot of traditional readers, we don't have as many as we used to. And we're missing an awful lot of kids entirely... Do I want to get rid of the Internet? Obviously, I don't want that because of all the amazing things it brings.

Human uploads have such a natural advantage over present-day people in the environment of space, it's exceedingly unlikely flesh-and-blood beings will ever engage in interstellar travel.

Adventure should be 80 percent 'I think this is manageable,' but it's good to have that last 20 percent where you're right outside your comfort zone. Still safe, but outside your comfort zone.

The only way I'm going to support my family is to tour. I love playing, don't get me wrong. That 90 minutes every night, that's free. We get paid to travel. But every night, I have to get myself locked in. There are a thousand people that don't want to be disappointed, because they have a lot of expectations.
