Of course, we could have a scenario where museums pay to revive us, and then keep us as an exhibit....

Chances are, it would look like most of what they found good and righteous in the world is gone. Would you inflict that on someone?

"The 'wild man' caught the imagination and attention of thousands of onlookers and curiosity seekers. He was then moved to the Museum of Anthropology at the University of California, Berkeley where he lived the remainder of his life in evident contentment...."

Well, people exposed to very low temperatures have ended up in states where they were considered clinically dead,

13.7C isn't "very low" for the relevant purposes, and she wasn't dead before she got cold like cryonics purchasers would be.

even though "volatile" functions had been interrupted

I'm not sure we can conclude this at 13.7C.

Interesting case, though.

Also, lower mammals have been frozen and brought back with no ill effects.

I've only seen this with cooling and super-cooling, not with freezing or vitrification.

Even if you place literally infinite value on being immortal, I imagine you'd rather spend the time wasted praying on something more likely to make you immortal, eg minimizing your chance of heart disease.

Even if the probability of being revived is sub-1%, it is worth every penny since the consequence is immortality

By that logic, one should pay to have prayers said for one's soul.

One could make a Drake's-Equation-style estimate of that "sub-1%" probability, but the dominant term is this: what are the odds that evolution, with no selection pressure whatsoever, has designed the brain so that that none of its contents are stored in a volatile way? Why write everything to disk if the computer never gets turned off?

Well, there's the fact that people have lots of seizures, which as far as we can tell are very chaotic patterns of electrical activity that scramble all information contained in ongoing oscillatory patterns. (Note the failure of spike sorting algorithms upon recruitment of neurons into seizure activity. http://m.brain.oxfordjournals.org/content/early/2015/07/17/brain.awv208.abstract) Not only that, but TMS (https://en.m.wikipedia.org/wiki/Transcranial_magnetic_stimulation -- effectively introducing large random currents in large chunks of brain tissue) doesn't seem to produce any long term effects as long as you don't start actually causing tissue damage through hydrolysis. On the molecular side, we know that our core personality is resilient to temporary flooding of the brain with a large array of different transmitter analogs, antagonists, and other chemicals. (All of the drugs that people do) Many of these chemicals are synthetic ones that we didn't co-evolve with. I think it's very reasonable to suspect that most of the important information that composes the individual is stored in genetic regulatory networks, and in the connectome. Chemical gradients aren't very information dense, and while we might a priori expect there to be a lot of information in ephemeral electrical activity, I think seizures and TMS are both good demonstrations that this information can at least be restarted given the structure of the network. Final thing to consider: there's much more individual variation at the level of anatomy than there is at the level of electrophysiological properties. There are a relatively small number of morphological categories of neurons (100s), that are fairly stereotyped across humans. But brain anatomy varies enormously from subject to subject. (Take into account that as a Cognitive neuroscientist, I'm probably biased in this regard) There's still some missing pieces, like working memory CAN'T be stored in the connectome because plasticity mechanisms an

The value of immortality does not seem infinite to me. Merely very large. The odds that magic or religion will save you seem vastly tiny. Sufficiently tiny that they are bad uses of time and energy even if the benefits are potentially very large.

I don't think it takes an degree in nano-tech or cutting edge medicine to be more confident in the power of future technology than in the power of praying for souls. Even if it is granted that there aren't great reasons for supposing cryonic preservation is viable, it is a huge and unwarranted leap to say that is as intellectually vacuous as the ideas of prayers affecting souls.

Can you point me to any positive evidence that the information needed for resuscitation survives death and freezing, rather than being carried in volatile state?

Without that, it seems to me that your argument boils down to "you can't prove it won't work." Which is true, but not much of an inducement to part with cash.

I understand this is from ages ago but is worth a response. See the Wiki page on Deep hypothermic circulatory arrest (a procedure used in some surgeries today):

Deep Hypothermic Circulatory Arrest (DHCA) is a surgical technique that involves cooling the body of the patient and stopping blood circulation.

The procedure requires keeping the patient in a state of hibernation at 12 - 18 degrees Celsius with no breathing, heartbeat, or brain activity for up to one hour. Blood is drained from the body to eliminate blood pressure. [emphasis mine]

This.

And, sticking to conceptual art, I'll happily defend John Cage's 4'33": a few sentences on a piece of paper that read like a stunt, but when actually experienced gave me a new understanding of the process of listening. If that's not "a skillful archer send[ing] an arrow into an exceedingly narrow target," I don't know what is.

The same is true of LaMonte Young's X For Henry Flynt. But you have to hear it. Reading about it won't do much for you.

Please point to at least one item available online which exemplifies that which you think I'm ignoring or missing.

Here are the four exhibits I saw last time I went to SFMOMA:

Modern Art cannot delight the untrained senses of a mere novice.

Whatever gets sophisticated critics to praise your rule-breaking is good Modern Art, and whatever fails in this end is poor Modern Art.

Both these statements are complete bullshit, as any visit to a modern art* gallery will confirm.

I think what you're trying to mock is conceptual art, a small sub-field of modern art, but your straw man bears so little resemblance to anything that actually happens in the art world that it's impossible to be sure.

*Scare caps are as bad as scare quotes.

the quality, production, expression, or realm, according to aesthetic principles, of what is beautiful, appealing, or of more than ordinary significance.

This definition has the advantage of eschewing the pointless essentialism of trying to decide whether any specific object "is" art. If you drive a nail with an unshaped rock, it's a tool, at least for the moment; if you get an aesthetic experience from something, it's art, at least for the moment.

There is no 'natural joint'.

In which case, "natural joint" is as good a category as any, no?

But sure, it's just shorthand, for me anyway.

Well, I'm glad to hear that I'm off the hook, since I have no problem regarding Python as art (although I'm a Ruby man myself). That said: do you really mean that, given the set { Python, The Rite Of Spring, Beethoven's Ninth }, the natural joint is { Python, Rite } | { Ninth }, and that this is so obvious that people who disagree deserve to be called rude names? If so, why? If not, what do you mean?

Also, it's been a while since I read the Tschai books, but my recollection is that The Dying Earth is way better.

(This would mark you as a gullible philistine, but you could argue it.)

I'd much rather be marked as a gullible philistine than be blind to the wonder of Joyce, Messiaen, and Rothko.
