Google's March 31, 2026 paper showed <500k physical qubits could break ECDSA-256 in ~9 minutes \u2014 a 20x reduction from prior estimates, inside a single block time. ~37% of Bitcoin's supply sits in addresses with exposed public keys. Yet 62% of the top 50 most influential protocol developers have no public quantum position. The dismissive camp outnumbers the urgent camp nearly 3-to-1. No current Core maintainer scores above a 2. Quiet building by the score-4 cluster (Wuille, Nick, Ruffing, Shikhelman) is necessary but insufficient \u2014 Bitcoin soft forks require public debate, community consensus, and political will. None of that is happening. BIP-360 exists but has no activation timeline. Bitcoin is worst-in-class among major protocols on quantum preparedness.",
