The real future is always stranger than we can imagine. Aging or rather the causes of aging are being identified, and we may be the last few generations to involuntarily die by time itself. Freezing is just a very expensive funeral choice if you disbelieve in coming back to life, but the technology for the frozen to come back is certainly less expensive than those that have been burnt...LOL.
Ray Kurzweil is a futurist, but AI singularity is probably unavoidable. When machines develop the capability of self evolution, Moore’s Law will decrease from 18 months to something significantly smaller. My guess would be in the range of the difference between chemical reactions to electrical ones... like milliseconds to nanoseconds, give or take a few orders of magnitude. Moore’s Law dropping from 500 days to half a day for a doubling would not be out of the potential realm. After a month of doubling what would the machine AI be thinking? Good luck!
Aubrey de Grey is on the cutting edge of aging, and he believes it is not impossible for the next generation to live a LONG TIME.
>>De Grey argues that the fundamental knowledge needed to develop effective anti-aging medicine mostly already exists, and that the science is ahead of the funding. He works to identify and promote specific technological approaches to the reversal of various aspects of aging, or, as de Grey puts it, “the set of accumulated side effects from metabolism that eventually kills us<<
