something really weird is going on cosmologically speaking, but isn't it the default assumption 'round these parts?
Not as far as I can tell. What do you mean?
Sorry, my sentence was unclear; "it" was referencing the belief that at least one intelligence besides us has already shown up or will show up somewhere in the universe at some point. It seems to me that most people, including most people on LessWrong, think this is likely.
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.
