I was writing a scene where a guy was choking another guy to death. You can go online and type 'chokeholds' and watch scenes where martial artists choke each other out. You can hear what noises they make when they go unconscious, see how their bodies flop and everything. YouTube is amazing for the more detailed stuff.

It's dangerous to be people-blind.

The true knowledge is not in the things, but in finding the connections between the things.

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.

Change creates fear, and technology creates change. Sadly, most people don't behave very well when they are afraid.

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.
