I read a theory that went something like this: Facebook got people to sign up to be organ donors. Then 23andme gets all the dna data. Then Google knows where all these people are, all the time with their smart phone location sharing services. So theoretically, there is a database that knows where the organ donors who might match a wealthy recipient are at all times. Did you know that the founder of 23andMe was married to the founder of Google? Kind of sci-fi, but still, dna science and technology are outstripping what an average person can understand at an exponential rate. How long before the "average" people are reduced to just labor, spare parts and, yes, even food! Hard to be optimistic about the human race sometimes.
