Best shot at immortality?

What looks, at the moment, as the most feasible technology that can grant us immortality (e.g., mind uploading, cryonics)?

I posed this question to a fellow transhumanist and he argued that cryonics is the answer, but I failed to grasp his explanation. Besides, I am still struggling to learn the basics of science and transhumanism, so it would be great if you could shed some light on my question.

I'm not that confident, especially as I have a sneaking suspicion that something really weird is going on cosmologically speaking, but isn't it the default assumption 'round these parts?

The default assumption is that there are (or will be) many other FAIs that light from our world-history will directly interact with? I didn't know that. It's certainly not mine. I thought it was more likely that we were for practical purposes alone. If you'll pardon the shorthand reasoning:

Fermilike considerations... epically unlikely that life emerges all the way to superintelligence takeoff
Anthropics and self indication and suchforth... most EBs where one superintelligence emerges will not be branches in which more than one universe emerges.
There are heaps of other superintelligences, with high probability all the other ones are in parts of the (broadly used) Universe that are causally inaccessible.
The physics is complicated, often speculative (by folks like Tegmark) and beyond me but it all adds up to "we're probably effectively alone in the universe as we see it".

So you think there are other FAIs out there that our civilization would encounter if we got that far? How much does this depend on probability that we are in a simulation or under the benevolent (or otherwise) control of a powerful agent and how likely would you consider it to be conditional on us not being simulated/overseen?

how likely would you consider it to be conditional on us not being simulated/overseen?

So it's possible that spacetime is infinitely dense and if you're a superintelligence there's no reason to expand. Dunno how likely that is, though blackholes do creep me out. Abiogenesis really doesn't seem all that impossible, and anyway I think anthropic explanations are fundamentally confused. If your AI never expands then it can't get precise info about its past, but maybe there are non-physical computational ways to do that, so the costs might not be worth the be... (read more)

I don't follow. Do you think intelligences would loudly announce their existence over a long enough time period such that we would know about it? It always struck me as more likely that AGIs were quiet than that they didn't exist. Remember, all those stars you see at night don't necessarily exist; could just as easily be an illusion. All it'd take is for one superintelligence to show up somewhere and decide that we weren't worth killing but that we shouldn't get to see what's actually going on as it gobbles all the unoccupied planets. There are various reasons it would want to do this. [ETA: The alternative, that abiogenesis is really difficult, strikes me as unlikely, and I have a very strong skepticism of anthropic "explanations".] [...] Hm, this might be a difference of perspective; I'm not very confident in the simulation argument as it's usually put forth. (I tried to explain some of my reasons elsewhere in this thread.) [...] (They don't have to be Friendly, they just have to be willing to trade.) I don't have a strong opinion either way. If we're being overseen then it seems true by definition that we'll run into other AGIs if we build an FAI, so I was focusing on the scenario where we're not being overseen/simulated/fucked-with. In such a scenario I don't know what probability to put on it... I'll think about it more.
