Why do you even bother?This is just another "Quantum computers will kill bitcoin!" type of topic,like many other topics here.Why to be afraid of a monster that doesn't even exist?
It doesn't exist yet, but it's true that we should plan for it. This is what the OP said:
I agree we shouldn't fearmonger about it, but safely and cohesively hard forking to make the necessary changes may not be an easy feat. Any hard fork release should have a very long activation time to minimize the possibility of a network split, so we should be talking about this sooner than later.
Given the size of the Bitcoin network and its rate of adoption, I think we should avoid emergency forks to whatever extent possible.
