People need meaning as much as they need air. Lucky for us, we can give meaning to each other for free. Just by being alive.

You don't want to stand too close to a robot arm; it can turn your head to mush.

How much change can a person absorb before everything loses meaning Living for its own sake isn't life. People need meaning as much as they need air.

I wrote a query letter to an editor - a friend of a friend. The editor called me an idiot, told me never to contact an editor directly, and then recommended three literary agents he had worked with before. Laurie Fox was one of them, and I've never looked back.

Looking ahead, future generations may learn their social skills from robots in the first place. The cute yellow Keepon robot from Carnegie Mellon University has shown the ability to facilitate social interactions with autistic children. Morphy at the University of Washington happily teaches gestures to children by demonstration.

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.

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.
