It's just a bunch of automated drones flying in formation. Trying to calculate their orbits ahead of time in any kind of detail would be a fool's errand, instead we'd just use solar light pressure to steer them as needed (the

I'm not sure why people seem so convinced that MNT is a hard requirement here. To be sure there are some components that require fine micrometer to nanometer level precision, but existing mechanical and/or chemical approaches do w

This technique is useful for general neuroscience purposes, yes. My point was just that it isn't what is critical to preserve for the sake of cryonics.

His criticism bad (as ever), since he assumes all information needed for nervous system function is the same as all information needed to replicate a given nervous system. Most of the information needed for function in any system is generic

Cool story, bro. Cryonics as it currently exists being profitable is 1) irrelevant to whether it works or not, and 2) a persistent myth.

I should also mention that the wood frog is really more a counterexample of vitrification. It forms ice (which they are adapted to tolerate, unlike us), but the interior or the cells remains a slightly more concentrated liquid. It is nowh

It's interesting that the comments by cell biologist Len Ornstein in that thread completely omit any mention of high osmolality vitrification, which is what is practiced in cryonics. I get the impression he is not aware of Fahy's

Not at all what was said. In fact, the whole criticism you linked to is about structure, and ways in which it is supposedly altered beyond repair. The notion that we are transient electric fields that fade the moment the brainwave goes flat

If you think the pursuit of immortality causes mental breakdowns, can you substantiate this with evidence from psychology journals? If not, this strikes me as unreliable folk wisdom. There is a lot of possible change that does not involve d

My gut estimate is that the chance is somewhere in the 1-10% range. I've been thinking about it for around 5 years. Part of why that number is so high is the relative lack of coherent and nuanced counterargument that demonstrates the critic

Personally, I'm glad to see cryonics being given more attention and discussion. It is a subject not well understood, even among biologists. If you think people undergoing it today are wasting their money (arguable, though I don't concede to

Isn't this more a question of the relative strength of objective evidence? I have a problem with the idea that hope in and of itself is a bad thing.

From what we do know, it's actually very reasonable. We know e.g. that memory survives hypothermic loss of electrical activity. So it is probably structurally based.

I think that if a cure for aging is invented tomorrow, I won't be able to benefit from it. Why? Because it will still be in clinical trials by the time I die. The simple solution is to pour money (and lots of it) into the goal of clinical
