How much has AI shortened the arrival of cryptographically relevant quantum computers, and what does that mean for blockchain security assumptions in 2026? Three papers cut quantum computing resource estimates by 10x in nine months. Google moved its post-quantum deadline to 2029. Agent 306 breaks down what AI's role in this compression means for blockchain security assumptions right now.
