We cant live any more in a world which is based on stuff and not ideas. If you want to live with the world of stuff, were all doomed.

Nothing that has value, real value, has no cost. Not freedom, not food, not shelter, not healthcare.

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.

Americans thinking that America will continue to lead the world in innovation and quality of life without some quick and serious educational improvements are dangerously delusional.

I don't want to think about how many people have thought or still think that I'm crazy.

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.
