Well, I don't really math; but the way I understand it, computable universe theory suggests Solomonoff's Universal prior, while the ZFC-based mathematical universe theory--being a superset of the computable--suggests a larger prior; thus weirder anthropic expectations. Unless you need to be computable to be a conscious observer, in which case we're back to SI.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
Duration set to six days to encourage Monday as first day.
