Dear David,
Please explain the claim : "We
observe that our universe uses a reversible computation". I do not see how this
follows from the observation that, on every observable scale, there is a
non-invertible (thermodynamic) arrow of time. I do not see how this is possible
if your
On the quantum scale, the dynamics are reversible, to a very high
level of accuracy. Irreversibility appears at macroscopic scales.
In answer to the original question, I would conjecture that an
evolutionary process is the only process capable of generating
complexity. Since we need a certain

No - I think in terms of ensembles of descriptions. Some of those
descriptions describe observers observing the descriptions. It then
becomes natural to ask what sort of description an observer might see,
given the description must describe the observer.
