pehaps, but the trend is there and its accelerating. I suspect that in short order (timeline unknown) we will actually have a legitimately marketable “life extension” option at which point its only a matter of degrees. the extra x years that you and I might possibly afford will eventually pale in comparison to the extra y years for the truly wealthy - at that point, generational wealth and power take on a wholly new and rather frightening dimension.
I admit… I may have a particularly bleak view of our possible futures, but an “undead” ruling class does not figure into any rosy endings that I can envision.
