> Wealthier people would have easier access to this tech. That would really mess things up I think.
How is that different from today's situation where wealthier people have access to better health care, while millions die from easily treatable or preventable diseases, especially in places such as Africa.
Or more simply, wealth is strongly correlated with life expectancy already, and there is a more complex casual link as well. (the daily stressors encountered by lower socioeconomic status people are the hidden cause behind a lot of illnesses).
