Has there been any talk about what to do with cryonically revived patients? If someone from the Renaissance or the time of the birth of Christ were to appear in today's world, he or she would obviously have a very difficult time fitting into modern society (ie. urban Chicago). However, he or she would probably be able to adapt much more easily into a rural community in a developing country, preferably one where it's inhabitants follow a culture that has resisted modernization and retained ancient traditions. Furthermore, it would be preferable for the community's inhabitants to speak a language that has retained conservative morphological and lexical features (ie. Icelandic).
Even someone born in the 1500's would have a difficult time living in modern society, let alone a caveman. He would probably be illiterate, from a rural background; and have no understanding of key issues such as democracy, separation of church and state, abolition of slavery, civil rights, heliocentric theory, etc. - In fact, even the most progressive, enlightened, intelligent, and educated individuals of the 1500's would find huge difficulties in adjusting to our modern world.
The average American male circa 2009 can be described as: white, completed high school or college, working hours 9 to 5, conservative, creationist, and Republican.
A person frozen today is unlikely to understand the cumulative amount of scientific and technological knowledge gained within the next few centuries (especially if the Singularity Prediction turns out the be correct). Nor is he likely to benefit from the cognitive enhancements made possible by the eventual convergence of neuroscience and nanotechnology. Hence, he or she would be unable to find a place in the new society in the same way a caveman would be unable to find a place in downtown L.A.
Rather, it seems likely to me that most revived patients would feel more comfortable living in specially-designed communities set aside by either Alcor or the future society as "nature reserves" for revived patients that would be the equivalent of modern Amish communities. Here, they will be protected from exploitation and provided with resources to lead independent lives. Meanwhile, the rest of the world would drift further and further away from us (exponentially of course) as our descendents become more and more god-like to us and the gap between homo sapiens (us) and homo superior (them) continues to widen.
