In an interview Max Tegmark said that he expected to have a "truncated" form of QI - he'd survive the quantum suicide experiment, but his brain would still deteriorate in any case until he eventually fades out ("like when an amoeba croaks" were his exact words, iirc) I think he also mentioned that

Actually the Beckenstein bound is proportional to the surface area of the universe. Nevertheless information capacity does go up with the volume of the universe, but not proportionally. On Wed, Nov 6, 2013 at 5:09 PM, LizR wrote: > That's similar to my pet theory for explaining the Beckenstein

Under the assumption that the universe is holographic then the limit in informational bits is 10^120. That limit is considered to be about the complexity of a neuron. Beyond such complexity the conjecture is that consciousness results. However, I am not aware of any evidence that this is the case.
