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.
