My prediction for 100/200 year's time: google/facebook search will combine with already patented genetic matching techniques (example); AI will take over, with each ruling its own fiefdom based on some existing corporate entity; each will steer different social/genetic matching systems to breed us like crufts animals. At least one of those AIs will just have fun trying to make REALLY weird-shaped people. (We do the same with dogs, after all.)
