I suppose that every time there is difficulty. I remember about Space Mountain: It took us ten years before we found the technology that would allow such a ride. And during these ten years, I had a model that I kept, waiting for the technology we needed.

Change creates fear, and technology creates change. Sadly, most people don't behave very well when they are afraid.

Right now, we have the most complex relationship with technology that we've ever had. Your regular person has more technology in their life now than the whole world had 100 years ago.

Robots are interesting because they exist as a real technology that you can really study - you can get a degree in robotics - and they also have all this pop-culture real estate that they take up in people's minds.

These days the technology can solve our problems and then some. Solutions may not only erase physical or mental deficits but leave patients better off than "able-bodied" folks. The person who has a disability today may have a superability tomorrow."
