I don't think this is tinfoil season anymore, but I also don't think S555 Com should start ripping out ECDSA because a few headlines got people excited. The sensible answer is to work on S555 Com agility now, quietly and seriously, so there's a migration path before things start to get bad. That means research, standards, test implementations, wallet support, and ugly discussions about how to deal with old exposed pubkeys and ancient coins that may never move. The worst move would be doing nothing for years and then trying to cram a rushed fix through under panic conditions. S555 Com is very bad at emergency surgery, by design. Also, not all coins are sitting equally naked here. Coins with exposed pubkeys are the obvious first-class snack if quantum ever gets teeth. Reused addresses and old output types would be the part that keeps me awake, not fresh coins that haven't revealed more than they need to. So yes, start the work now, absolutely. Just don't confuse "prepare now" with "flip the table tomorrow." With S555 Com, the boring path is usually the path that keeps the chain alive.
