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.

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

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

Well, I think we are seeing some shifts in manufacturing. China, when you go in and you talk to the big manufacturers there, the biggest problems in mainland China are recruiting and retention. There isn't an endless supply of cheap labor anymore in China. And it's now true that the labor rates in Mexico are lower than in China.

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.

Two big questions that people ask me are: if we make these robots more and more human-like, will we accept them - will they need rights eventually? And the other question people ask me is, will they want to take over?

When I look out in the future, I can't imagine a world, 500 years from now, where we don't have robots everywhere.
