How can Asics be created in a "decentralized way" if not all people can become manufacturers or if the manufacturers do not have the same access to the raw materials needed make them?
For a network that aims to leverage the miners by having the coin holders have voting power, they sure are trying to settle the issue outside the network.
A change in the mining algorithm is not a "power move" if the community is in consensus.
That scenario is years and years into the future. IMO, decentralized doesn't require "all", just a subset. Obviously, the larger the subset, the higher the degree of decentralization. Still though, even a small number like 100 is 100x more than 1.
It could be considered a "power move" in that its purpose would be solely to obsolete the
current asics in production/in the field (especially knowing it's only a delay, not a solution). Reminiscent of when Ethereum hf'd to rollback the DAO hack (even though [majority] community consensus was there).
