It's hard to wipe your eyes when you have whirring buzzsaws for hands.

Zombies, vampires, Frankenstein's monster, robots, Wolfman - all of this stuff was really popular in the '50s. Robots are the only one of those make-believe monsters that have become real. They are really in our lives in a meaningful way. That's pretty fascinating to me.

Personally, I'm not afraid of a robot uprising. The benefits far outweigh the threats.

It's hard to guess how smart the machines are, but a good rule of thumb is that they're always smarter than you think.

Luckily, unreasonable expectations go hand in hand with naive young scientists. The more naive the better - otherwise we would never have the audacity to try and build a 22,000-mile-high space elevator or some sprawling underwater hotel.

Sometimes a technology is so awe-inspiring that the imagination runs away with it - often far, far away from reality. Robots are like that. A lot of big and ultimately unfulfilled promises were made in robotics early on, based on preliminary successes.

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.
