Weband quantum-AI (QAI) represent a totally new and effective vector of cryptanalytic attack. Much as modern AI successfully completes browser search phrases, so it is increasingly capable of guessing a rather narrow a-priori list of plausible plaintexts. This guessing is most effective over device cryptography where the message space is limited.
