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.

Meaning is like pornography, you know it when you see it.

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

Programmed by quanta, physics gave rise first to chemistry and then to life; programmed by mutations and recombination, life gave rise to Shakespeare; programmed by experience and imagination, Shakespeare gave rise to Hamlet.

We couldn't build quantum computers unless the universe were quantum and computing. We can build such machines because the universe is storing and processing information in the quantum realm. When we build quantum computers, we're hijacking that underlying computation in order to make it do things we want: little and/or/not calculations. We're hacking into the universe.

At some point, Moore's law will break down.

By separating the function of adaptation from the function of maintaining the integrity of individual genes, sex allows much greater diversity while still keeping genes whole. Sex is not only fun, it is good engineering practice.
