Having kids is the old-school form of immortality. I imagine many of those other billionaires are thinking about their dynasty.

Their kids will need SENS ~30 years after they do.

I get that the typical plan is to have a dynasty via grand kids, great grand kids, etc, but it's dumb to ignore SENS.

Just as an FYI - I believe you're using SENS as in:

"SENS stands for Strategies for Engineered Negligible Senescence, a detailed plan for reversing human aging. It is an engineering approach that seeks to slow and then halt aging processes that are the side effects of our body's metabolic cycles"

Correct?

[xenophanes]

Correct.

It's not dumb to ignore it if you believe it to be a fool's errand.
