You're the only one I've read use the term commoditization for Bitcoin mining's future--what do you mean? And can you clarify how it fixes the centralization problem?
The usual term is commodification, meaning affordable and
efficient consumer-level ASICs
Interestingly just now Core devs have tossed up an idea
of changing the PoW algo to prevent a patented mining optimization.
So it is not totally clear if Bitcoin Core is a permissioned
ledger.
