If we're in a bubble, it's the weirdest bubble I've ever seen, where everybody hates everything.

When you're dealing with machines or anything that you build, it either works or it doesn't, no matter how good of a salesman you are.

I've been a customer of the top venture capital firms, so I know exactly what they do and don't do.

At Microsoft, they all rock back and forth like Gates, they wear the same glasses, they have the same hair style. Maybe they grow them in tanks.

A lot of things you want to do as part of daily life can now be done over the Internet.

More and more major businesses and industries are being run on software and delivered as online services - from movies to agriculture to national defense.
