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

I consider high-speed data transmission an invention that became a major innovation. It changed the way we all communicate

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.

You have teenagers thinking they're going to make millions as NBA stars when that's not realistic for even 1 percent of them. Becoming a scientist or engineer is.

I don't work on a project unless I believe that it will dramatically improve life for a bunch of people.

I think we have a society which is spending more and more of its money on healthcare as a percent of GDP as a percent of a lot of things. I think that's a measure of success.

Most of the time you will fail, but you will also occasionally succeed. Those occasional successes make all the hard work and sacrifice worthwhile.
