Yes, I am a quantum mechanic! Those darn quantum computers break all the time.

If you take a more Darwinian point of view the dynamics of the universe are such that as the universe evolved in time, complex systems arose out of the natural dynamics of the universe.

If you wanted to build the most powerful computer you could, you can't do better than including everything in the universe that's potentially available.

One of the things that I've been doing recently in my scientific research is to ask this question: Is the universe actually capable of performing things like digital computations?

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

The primary consequence of the computational nature of the universe is that the universe naturally generates complex systems, such as life. Although the basic laws of physics are comparatively simple in form, they give rise, because they are computationally universal, to systems of enormous complexity.

Another feature that everybody notices about the universe is that it's complex.
