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.

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.

The goal for many amputees is no longer to reach a 'natural' level of ability but to exceed it, using whatever cutting-edge technology is available. As this new generation sees it, our tools are evolving faster than the human body, so why obey the limits of mere nature?

You want to know what a robot's designed for. And if it's doing something outside the scope of what it's made to do, you should be very suspicious.

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

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.

Some unspoken human communication is taking place on a hidden channel. I did not realize they communicated this much without words. I note that we machines are not the only species who share information silently, wreathed in codes.
