Memories fade but words hang around forever.

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.

Technology changes, but people stay the same.

Robots should stand up for themselves and not try to be humans. They should either utterly destroy us or protect us from aliens. And vampires. And pirates.

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.

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.

There are no truer choices than those made in crisis, choices made without judgment.
