People need dramatic examples to shake them out of apathy (yes I just quoted Batman Begins), a fork that is polished and ready to be deployed immediately in reaction to one of the predictions would have a much higher chance of success than a contentious hard fork deployed at an arbitrary date.
Tell me why I'm wrong/midwit and why we should just hard fork in the next 15 days with a dogshit name like Bitcoin Blake2b and the battle cry of LEEEEROOOY JENKINSSSS!!!
