When it comes to their capacity to screw things up, computers are becoming more human every day.

The history of the universe is, in effect, a huge and ongoing quantum computation. The universe is a quantum computer.

It's also a reasonable scientific program to look at the dynamics of the standard model and to try to prove from that dynamics that it is computationally capable.

Quantum mechanics is weird. I don't understand it. Just live with it. You don't have to understand the nature of things in order to build cool devices.

Computers are famous for being able to do complicated things starting from simple programs.

Of course, not everybody's willing to go out and do the experiments, but for the people who are willing to go out and do that, - if the experiments don't work, then it means it's not science.

All physical systems can be thought of as registering and processing information, and how one wishes to define computation will determine your view of what computation consists of.
