Just wondering, seems like GPU's are taking off more than ever because of machine learning, VR, etc.. and it seems like they are never going away.
But ASIC's seem to be too centralized and sway power too much, like this one man in China that builds 70% of all Bitcoin ASIC's.
I know people talk about this a lot but I wonder why it's not considered more seriously.
I know that eventually people would make an ASIC no matter your algo, so could you change your PoW every X years to focus on GPU usage, shutting out ASIC miners again and again?
Of course you can't just switch from one algo to another in one block, so it would have a be a transitional change over a period of blocks where the new algo is phased in.
I know nothing I have said or asked is new, what I want to know is if a change of algo will ever be seriously considered? Perhaps even as a long term change every X years depending on the speed of ASIC development.
