ChainCatcher message, based on the article released by IBM on the progress of quantum computing research, Musk inquired with Grok about the probability of quantum computing breaking the Bitcoin algorithm (SHA-256).

Grok replied that according to assessments from NIST, IBM, and expert surveys for 2025, the probability of quantum computing breaking SHA-256 is "almost 0% in the next 5 years, and will be below 10% by 2035." This requires millions of error-correcting qubits; while current systems support a maximum of about 1,000 noisy qubits. The hash value of Bitcoin remains secure at present.
