Elon Musk often advocates looking at problems from a first principles calculation rather than by analogy. My question is what does this kind of thinking imply for cryonics. Currently, the cost of full body preservation is around 80k. What could be done in principle with scale?

Ralph Merkle put out a plan (although lacking in details) for cryopreservation at around 4k. This doesn't seem to account for paying the staff or transportation. The basic idea is that one can reduce the marginal cost by preserving a huge number of people in one vat. There is some discussion of this going on at Longecity, but the details are still lacking.
