I think relatively few people share this kind of existential dread. It actually has never crossed my mind personally. If I think 500 years into the future, what would be great is if my descendants are ample and thriving, and my values are upheld. That feels like such a win to me. The fact that I won't physically be there is irrelevant. On the other hand, artificial continuation of an otherwise impact-less life sounds awful to me. I suspect that billionaires (certainly, the 2 that I have some insight into having worked for them) think much more about impact they are creating, than some sort of "hang on forever like a barnacle" type of existence.
