A singularity is necessarily a recursive self improvement process because once
we achieve superhuman intelligence, those intelligences will be able to make
further improvements faster than we can. Legg proved  that an intelligence
(using the universal definition ) cannot completely predict the behavior of
a greater intelligence. Thus, RSI is experimental at every step. It is an
evolutionary algorithm that favors rapid reproduction and acquisition of
computing resources. Evolutionary algorithms, whether based on DNA or not,
require death, and will favor intelligences that fear death.
One could program an uploaded mind in one of two ways to solve the problem.
One is to remove the fear of death. But such an intelligence would have no
sense of consciousness. It would reason that one set of memories is just as
good as another, and die. The other is to achieve immortality by backing up
memories, even if they are no longer useful. But this wastes scarce computing
resources, which would slow more meaningful growth.
Perhaps there is another path to immortality and unlimited growth of
intelligence, but I don't know what it is. Then again, if I was running a
simulation of the universe, I would already have the collective memories of
all the humans on earth, none of whom were programmed to know they were
already immortal, because it would have messed up the evolutionary algorithm I
As a product of evolution, I find this a very thought provoking article. But
I don't know what to do about it, if anything. If I were not a product of
evolution, would I care about my own life?
