Homomorphic encryption and similar techniques in this paper are just getting going. They are impressive technologies. However, they often take 100x the compute of "regular" systems with encrypted networking. This is probably the main blocker for these types of technologies. Until and unless insurance companies mandate these technologies because they are tired of paying out for their customers getting hacked, they probably won't be deployed. Probably for the best. Most devs can barely make code without advanced math and encrypted data work, let alone these types of advanced platforms.
