I don't think that's the right way to do Bayesian updating in the presence of observer-splitting.
Imagine I sell you a device that I claim to be a fair quantum coin. The first run of the device gives you 1000 heads in a row. You try again, and get another 1000 heads. You come back to my store to demand a refund, and I reply that my fair coin gives rise to many branches including this one, so you have nothing to complain about. Do you buy my explanation, or insist that the coin is defective?
I started to write a rebuttal, but it's quickly becoming clear to me that I don't have a systematic way of reasoning about this topic. I don't necessarily agree with you, but I need to give the matter a lot more thought. Thank you for giving me something to think about.
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.
