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.

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.

As a kid I wanted to write science fiction, and I was never without a book. Later I really got into being a scientist and never thought I'd be writing novels.

A soul isn't given for free. The races of men fight each other to the death for the honor of being recognized as human beings, with souls.

There are an endless number of things to discover about robotics. A lot of it is just too fantastic for people to believe.

Across the sea of space lies an infinite emptiness. I can feel it, suffocating me. It is without meaning. But each life creates its own reality.

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.
