I don't. A human is not necessary to the process. A human is necessary for the process to be done well. And if the NSA has broken its own encryption, to the extent that it can read past traffic, call the IMU because there are some Field's medals that need handing out.
The UK equivalent of the NSA invented both RSA encryption and DH key exchange years before any of Diffie, Hellman, Rivest, Shamir, or Adleman did their work. No Fields medal per se, but two Turing awards...
I think the odds that the largest employer of mathematicians in the world is secretly sitting on ground breaking fundamental math is pretty high.
That will still happen, but it will happen _after_ AI processes ${HUGE_NUMBER} of data streams simultaneously to pick out the interesting ones. Human intelligence and AI are complementary in this regard. We are better at the fine detail. They are better at the raw throughput and parallelism. Both types of brain working together to spy on you should terrify you.
I dislike the premise behind "it's all encrypted and we cannot do that anymore" since we have no idea what capabilities an agency like NSA has now or could have in the future. If their capabilities grow perhaps they can replay all that saved encrypted data from their Utah Data Center and throw it into AI for analysis. Why do you assume a human has to be involved in the judgement process for it to be taking place?
