Another question that comes up is the possibility of growing human meat. Of course, it would be completely possible for human cells to be taken through the same process of in vitro meat production. It’s possible that one could even eat oneself…in some sort of closed-loop fantasy of the uber vegan.  Maybe future space-farers will grow meat in a semi-sustainable fashion. Obviously, this idea won’t be entertained by any commercial entity, but it’s worth stating that it is possible and that human meat has been consumed by other humans in the past. So the possibility exists.  Am I on a list yet?
