Hearing some industry insiders say in interviews that quantum defense isn't that complicated, this dismissive attitude is actually the most dangerous. Quantum computing is indeed portrayed as very mysterious right now, but we must not become complacent— the key issue is that decentralized network systems face unique risks that traditional financial systems would never encounter. Once these massive distributed systems are threatened at the quantum level, there is no centralized rescue channel to back them up. The attitude of technical leaders towards such systemic risks determines whether the entire ecosystem can truly build long-term defense mechanisms.
