Yes, this could be an issue. We might want infinite algorithmic
complexity. But I wonder if not quantum noise might be powerful
enough to create it.

Algoritmic complexity (the complexity of something is defined as the
length of the shortest program + data that generates it) is one of the
better complexity measures around, but it is not good enough. If I sit
in a box and come up with a great fantasy world, has the information
and complexity in the box not increased? I think AC fails here because
it is a static measure, intended to denote the complexity from a
"God's eye perspective". What we need is a measure that can denote the
increase in meaningful information.

Hmm... time to go home. It seems my mind is getting very
chaotic. Perhaps good for my algorithmic complexity.
