Nice, but we're years away from seeing that in a miner.
Well, thinking about it in an optimistic way. If someday in a year or two if we get to see some hardware running on Asic boost as well as 7nm tech. It'll be like next level of efficiency in mining and network hashrate of aboth 10Eh/s. But only if IBM is generous enough to share some details on their 7nm.
I really hope from the bottom of my heart that this happens.
Indeed centralization is an issue but still, it can restore home mining to an extent.
