I've been thinking a bit about how living on could play out without being too futuristic with the technology. Coming back from cryopreservation is probably many decades out but we are quite close to being able to make a virtual AI version of you, working a bit like an actor playing you. Tech like Heygen is quite good with avatars and voices, and chatgpt type AI could pretend to be someone in a pretty terrible way just now but that stuff will get better and the virtual you could act as an assistant, learn your ways and help out.

Then when the physical you passes and maybe is cryopreserved the virtual you could conduct the funeral type service and say hey guys physical tim333 is gone but I'm still here and you can chat to me on the web etc. Virtual you could maybe have some investments and could buy gifts for the grandkids and post on HN etc. Then in a few decades virtual you could get data from cryopreserved you and incorporate it.

Perhaps it could be done as a startup?
