Cryopreservation, or the posthumous freezing of the body/head/or brain for future revival, has been around a long time. It's either visionary and ahead of its time, or highly speculative naively hopeful, or both. If, like me, you're curious about the furthest edges of human, technological and scientific possibility, you've probably already heard of it.
I'm not knowledgeable enough about biology to know whether cryopreservation was even theoretically possible or more of a techno-utopian fantasy. But now it looks like it might be technically feasible.
Between feasible cryopreservation, anti-aging research, and medical/engineering/scientific a.i., we're once again playing ethical catch-up with our technology and knowledge.
Outside of a smattering of individuals, institutions, academic journals and literature, our species doesn't do a very good job overall of thinking about the future.[1] Much of our attention is focused on the present. Future oriented minds are highly outnumbered by politically active forces of reaction whose anticipated future is limited to a recapitulation of the past or idealizations of the past. A necessary consequence of this lack of cultural foresight is that we stumble into problems repeatedly, causing ourselves needless harm.
Will lifespans of 150 or 200 or 500 years be possible within most of our lifetimes? Will death become voluntary this century? What does this mean for everything that we do and how we think about ourselves?
[1] We already don't do an adequate job teaching literacy, let alone specific literacies like history, science, or moral/ethical literacy, or philosophical literacy, but in light of the increasing rapidity of technological change, a more futures literate population would be desirable. At least according to my political lights, an intellectually serious society would have already established futures literacy as a goal for K-12 education and beyond.
