As a society, I think we express our cultural mores through our politics. We're trying constantly to figure out what's OK and what's not OK. And it's hard, because our society is constantly buffeted by gale force winds of technology. Things are always changing.

Memories fade but words hang around forever.

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.

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.

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.

To survive, humans will work together. Accept each other. For a moment, we are all equal. Backs against the wall, human beings are at their finest.

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