In some cases, inventions prohibit innovation because we're so caught up in playing with the technology, we forget about the fact that it was supposed to be important.

As we move towards 8 or 10 billion people on the planet, there's a little less gold per capita. Each one of us will continue to be fighting over an ever smaller percentage of total resources. This is not a happy thought

Whatever the marketplace, if talented people are given resources, they're going to keep driving us to having better, simpler, cheaper solutions to problems.

We are in a race between knowledge and catastrophe. If we keep track of what is important, never lower our standards or forget why we are here, we have the ability to determine the fate of the world.

People take the longest possible paths, digress to numerous dead ends, and make all kinds of mistakes. Then historians come along and write summaries of this messy, nonlinear process and make it appear like a simple, straight line.

Sometimes we crash and burn. It's better to do it in private.

My biggest failure is I have too many to talk about.
