Suppose you're a human, and you think we're onto something with modern physics. Humans have a brain that does not exceed a meter in radius. Humans have a brain that weighs less than 100kgs. By the Bekenstein bound, we know the average human brain could have at most 2.6*10^42 bits before forming a black hole, and for the upper bounds I gave, that number is larger, but note, it is still finite.
Now let's say you want to make decisions. What does it mean to make decisions? That's tricky, but we can say it has something to do with performing actions based on sense-perceptions. Let's assume that you are fully aware of your... (read 278 more words →)
Besides cryonics, if you can "revive" someone by figuring out the exact parameters of our universe, simulating history, and thusly finding the people who died and saving them, this changes the calculus further, as now we need to consider extending the lifespan of everyone who ever lived.
Mind uploading, besides directly increasing lifespan, could also result in copies and branches of selves. I find it extremely difficult to reason about the utility of having N copies of myself.
It's unclear to me if this possible, but there's at least uncertainty for me here, when we talk about superintelligence.
