> What would change if we could live for even just a million years? ... First, tenure in academia would have to be capped. Universities would have to limit faculty appointments to a century at most in order to refresh their talent pool and mitigate old-fashioned education and research dogmas.... > An extended life experience could make us wiser and more risk-averse since there is much more at stake.... > Increasing our fertility period in proportion to our life span will bring the risk of overpopulating Earth. With the current birth rate per person, the number of million-year-old people could increase to the untenable level of a hundred trillion. Moderating that would require a public policy that limits the birth rate to the desired level. So basically, social ossification and stasis. You'll also have voters who made up their minds on all the political and social issues half-million years ago, and see no reason to change their minds (just like you have people who did the same a half-century ago). I think any kind of extreme longevity scenario will result either ossification or a re-invention of death under another name (e.g. a memory reset). A finite thing can only go on forever by settling into some kind of repetitive cycle, otherwise it will quickly exhaust its memory.
