Nothing in life is certain except death, taxes, and the second law of thermodynamics.

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.

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

There are considerable advantages to using many degrees of freedom to store information, stability and controllability being perhaps the most important.

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.

I have not proved that the universe is, in fact, a digital computer and that it's capable of performing universal computation, but it's plausible that it is.
