Yeap! It’s also important to separate two distinct events: the day a cryptographically relevant quantum computer actually comes online, and the day the world realizes one is coming.
The first is Q-day, but the second moment matters just as much (let’s call it OH-F**K day), the day the majority of the market wakes up to that inevitability.
Protocols need to harden themselves against both timelines. Markets and ecosystems move on sentiment way more than science. A credible/fake announcement, leaked milestone, opaque demonstration of quantum advantage will trigger a chain reaction well before the first real break happens.
