Its was far more disturbing when asics first came online, i regret that pow change didnt happen in start. I know a lot of people have they money
in asics and for that reason dont want algo change, but as it is, whole bitcoin community is in the hands of few asic producers, which is one of the worst scenarios possible.
If we could restart, how would you change it to prevent centralization? Centralization is largely due to low cost power, ASIC's and access to ASIC's aside.
