What If Cryonics Wasn't Cold?

The purpose of cryonics is to preserve the body and brain with as little small-scale damage as possible for revival via plausible future technologies, most likely medical nanomachinery. To save lives, in other words. Depressed Metabolism has previously argued that it's something of an accident of history that the cryonics industry uses cold-based preservation rather than a form of warm chemical preservation, and here elaborates on future molecular nanotechnologies that may achieve warm biostasis: "To see how one approach would work, imagine that the blood stream carries simple molecular devices to tissues, where they enter the cells. There they block the molecular machinery of metabolism - in the brain and elsewhere - and tie structures together with stabilizing cross-links. Other molecular devices then move in, displacing water and packing themselves solidly around the molecules of the cell. These steps stop metabolism and preserve cell structures."
