Elon Musk is raising new questions about Bitcoin’s long-term safety in the face of rapid advances in quantum computing. The Tesla and SpaceX CEO turned to his AI chatbot, Grok, to find out how likely it is that Bitcoin’s SHA-256 hashing algorithm could be cracked by powerful quantum machines.His question came just as IBM revealed major plans for its next-generation quantum system called Blue Jay, which is expected to reach 2,000 global qubits by 2033.Grok Predicts Low Risk, At Least For NowAccording to Grok, the risk of Bitcoin’s encryption getting cracked by quantum computers is very low over the next five years. The AI estimates the chance remains close to zero during that period.But when looking out to 2035, the probability goes up slightly—though it still stays under 10%. These numbers are based on expert assessments and current quantum capabilities.Based on 2025 assessments from NIST, IBM, and expert surveys, the probability of quantum computing cracking SHA-256 (via Grover’s algorithm, reducing preimage search to ~2^128 operations) is near 0% in the next 5 years and
