I'd rather have half of my idea change the world than my whole idea be a few papers in a journal.

If we are machines, then in principle at least, we should be able to build machines out of other stuff, which are just as alive as we are.

I begin by looking for megatrends, changes in the world that will create major new demands. My goal is to create a company that can be there to meet those demands.

I always tell people, it's never too late to start saving for retirement. It's not that important how much you have already saved. What's important is that you start saving. And save as much as you can. You will be amazed at how quickly it will build up.

When people lose faith in the idea, you have to let them go, because they start to undermine it for everyone else.

If you're doing something radically new, you need a team that's willing to go on a ride that's very different from anything they've encountered before.

My talent is getting things to work that people think are many decades in the future. I say we can make them happen now.
