This unofficial Bitcoin roadmap and the official ETH (Ethereum) PQ roadmap present two very different philosophies.
* As one would expect the ETH PQ roadmap is ambitious bordering on hubristic. It proposes a very short timeline and aims to deploy protocols that will to push the frontiers of current technology.
* This proposed Bitcoin roadmap is conservative and focused. It is designed around managing risk and hedging against unknowns using currently available tech.
Reminds me of that Arthur C. Clarke short story [0]:
> "We realize now that this was our first mistake. I still think that it was a natural one, for it seemed to us then that all our existing weapons had become obsolete overnight, and we already regarded them as almost primitive survivals. What we did not appreciate was the magnitude of the task we were attempting, and the length of time it would take to get the revolutionary super-weapon into battle. Nothing like this had happened for a hundred years and we had no previous experience to guide us."
