A couple of videos on economics and engineered longevity, by G. Stolyarov II and Aubrey de Grey: "Mr. Stolyarov discusses how indefinite human life extension will bring about numerous economic benefits to human beings and human civilization. He approaches the subject from the standpoint of the idea of time preference and the time horizons that would be greatly expanded for humans who live much longer. Furthermore, indefinite human longevity will enable humans to confront major existential threats - such as the threat of a meteor impact or a new ice age - that are beyond the timeframe of the individual lifespan today. ... Radical life extension would have a huge impact on the economics of society - possibly a dangerous one. Aubrey de Grey explains why he remains optimistic that the economy would adapt well to the drastically new paradigm presented by human immortality." Sadly, there's always someone out there who thinks that extended healthy human life is dangerous, despite the evidence of past centuries and many regions of the world that show greater life expectancy walks hand in hand with economic growth and higher standards of living. This is one of the reasons that advocacy for longevity science is even necessary in the first place. Nonetheless, the two upward trends of longevity and wealth are entwined and drive one another wherever they can start. But despite living in an age of change, so very many people fear change to the point of rejecting it even when it is overwhelmingly positive.
