If we're being overseen then it seems true by definition that we'll run into other AGIs if we build an FAI
This seems likely but is not true by definition. In fact if I were designing and overseer I can see reasons why I may prefer to design one that keeps itself hidden except where intervention is required. Such an overseer, upon detecting that the overseen have created an AI with an acceptable goal system, may actively destroy all evidence of its existence.
True, mea culpa. I swear, there's something about the words "by definition" that makes you misuse them even if you're already aware of how often they're misused. I almost never say "by definition" and yet it still screwed me over.
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.
