Definitions for this question:

• "ASI" = an emergent artificial intelligence with power or capabilities beyond human understanding

• "doesn't wipe out humanity" = humans still exist, and they still have biological bodies (modifications okay) and individual consciousnesses

• "natural death" = sickness, old age, genetic disorders, etc. (Doesn't include: accidents, war, foul play, divine reckoning of any variety, etc.)

• "be cured" = at minimum, all consenting humans are protected from natural death (by oversight, treatments, augmentation, or whatnot), and at least 50% of humanity's living population has been offered said protection

• "within 5 years" = 5 years from ASI, as best as can be determined

This resolves N/A if ASI is not achieved by market close or humans are all wiped out. Close date is highly speculative and may be adjusted if there's reasonable potential for a non-N/A resolution.

As presumably this question is regarding post-Singularity events, my attempts at definitions are likely insufficient. Take to the comments if you have suggestions for improvements that are in the spirit of the market.
