>Yes, I think it is extremely unlikely people will figure out thousand-year lifespans.

Why? Do you think this would withstand a thousand years of human ingenuity? I'm confused where you're getting this very confident prediction.

It also still seems to me that long lifespans are extremely desirable, albeit difficult to obtain, and I'm not sure whether you agree. This is relevant because if we want to decide e.g. where to put research effort, it's useful to know what we want.

The article you linked is kind of long, and looks like it mainly consists of sneering at various people; could you point to the part that's relevant? All I saw was some stuff about Alcor messing up a preservation, which is pretty unfortunate, but not really strong evidence that they have bad motivations.

I can't know what anyone's motivations are, but I can feel pretty confident that they are selling false hope based on bogus science.

This is genuinely not obvious to me. What convinced you of this? Or, what do you think the world would look like if there were people who actually had a strong, reasonable, non-insane suspicion that they could do the things that cryonics people claim to be able to? To me, it looks like we are living in that world. Have you e.g. looked through the information, studies, and arguments on the Alcor website?

Well, you don't want to read the article I linked. Why would I want to read a bunch of studies published by someone with an obvious vested interest in convincing me cryogenics is not nonsense?
