I'm not suggesting that, at all. I just don't like the framing that any new screening process must be part of a "quest to live forever" instead of a quest to e.g. live long enough to go to your kid's wedding.
I think the point is more that rich tech folks (like many people) think doing more testing must be good even if there's no scientific evidence to support that conclusion - the difference is rich tech folks can afford it anyways, and they're going to be very loud about it.
