Thinking of the universe as a computer is controversial.

Some folks think life and technology and mind can keep expanding forever. Others say it can't. We are still not clear on that.

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

Instead of having to be a member of the Royal Society to do science, the way you had to be in England in the 17th, 18th, centuries today pretty much anybody who wants to do it can, and the information that they need to do it is there.

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.

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

Of course, one way of thinking about all of life and civilization is as being about how the world registers and processes information. Certainly that's what sex is about; that's what history is about.
