That’s an “appeal to authority” logical fallacy. Quantum needs evidence for it’s extraordinary claims: We don’t freak out about teleportation but that tech would be even more disruptive. The quantum threat isn’t proven. The recent ‘15-bit encryption cracked’ experiment turned out to be false. Shor’s algorithm needs millions of stable qubits; current machines have thousands of noisy ones. Bitcoin’s secp256k1 is safe for the foreseeable future.
