elon just said longevity is coming. i've been digging deeper lately into how to prepare for it. it all sounds kinda crazy now, but i think all of this will be pretty normalized in the next couple of years with how fast AI is evolving. dying in the next 10 years or so, just before immortality becomes possible, would be the most tragic timing ever imo. so i want to do everything i can to give myself and my loved ones the best chance of making it there. here's how i'm preparing. the must-haves for me: 1. cryonics you pay a company to preserve your body or brain after death until technology exists to revive you. in the US, there are several providers. the biggest one is Alcor. in Germany, the relevant provider for me is Tomorrow Bio. i haven't set this up yet, but i'm getting everything ready now. i always assumed you needed a huge amount of cash upfront. but it's actually not that bad. here's the breakdown: Tomorrow Bio costs €50/month for membership and €200k for whole-body preservation (it's similar for Alcor). the membership basically makes sure a team is on standby to respond when you die and prepare you for transport and preservation. (that's just 2 netflix subscriptions. worth it if you think about it.) the €200k sounds like a lot at first. but that can actually come from life insurance. if you're in your 30s like me, term life insurance could cost around €10–20/month. if you die before the policy ends, say at 65, it covers the €200k. meanwhile, you would build up €200k on the side. if you outlive the policy, you can pay the fee yourself. for my parents, who are past 65, i'd focus on having the funds ready directly. at that age, you could also get whole life insurance, but it would cost several hundred per month. for my kid, it's trickier. some providers don't accept under-18s. Alcor and Cryonics Institute in the US do, though, so i'll probably set it up with one of them until he's 18 and then see. another option is a much cheaper provider called Cryonics Institute. they charge only around $28k. but they basically only do the freezing, and you have to organize the transport yourself. and the long-term funding is less secure, which means they might run out of money at some point, and your relatives would then need to pay to keep you frozen. although this might not even be such a big issue at the speed at which everything is evolving now. 2. cord blood + tissue banking i think this is a total no-brainer if you're planning to have a kid. we did this for our son through Vita 34 in Germany, and i'm super glad we did. and we'd of course do it again if we have more kids. after birth, they collect blood from the umbilical cord and placenta, plus a piece of cord tissue. then they freeze it to save the stem cells. the idea is to keep those cells available for medical uses, including potential future therapies. so it's kind of an insurance even before the cryonics insurance. for us, it cost €1,670 upfront + €180/year for storage. so totally doable. in the US, there are many providers too, like CBR, ViaCord and Cryo-Cell. some other things i'm looking into: → sperm / egg freezing: keeping the option of having more kids later. → iPSCs: reprogramming blood or skin cells into stem cells for potential future repair. still mostly research, but interesting because my own cord blood wasn't stored. → blood banking: freezing a sample for potential future testing or making stem cells. → microbiome banking: preserving your gut bacteria for possible use after heavy antibiotics. → baby-tooth / dental stem cells: banking cells from inside baby teeth or wisdom teeth. again, i think it all kinda sounds crazy now. but with how fast AI is evolving, i think the next few years will make it much clearer how possible this future is becoming. and i want to give myself and my family the best chance of being around for it. i think it's actually kinda stupid not to.
