I'm going to say it again in this case: if 1 powerful company have protected intellectual property related to significant performance gains for mining chips (i.e. SHA256 ASICs), then that company essentially owns the mining market.
That is terrible news for Bitcoin's security model, as Intel could control the whole mining market and in turn control Bitcoin software development. Bitcoin's market value would be seriously impacted, and unless a similar 35% could be found in an unpatented method (its unclear whether Intel's technique could be used with the overt form of ASIC Boost), a PoW hard fork would be inevitable.
I think this situation is pretty complicated. Bitcoin's mining has been heavily centralized for years, with Bitmain producing almost all hardware and most mining power being concentrated in China (some even say that it's controlled by just a few people). And yet we don't see any blatant attempts to takeover the network via hashpower - most of the recent attacks were social - Bcash and other forks, spam transactions, FUD, sockpuppets, etc. I feel like Bitcoin is already very robust, and potential security gains from hardforks might not be as big as they sound. So, I'd gladly support a PoW change if it was proposed by Bitcoin Core, but I don't think that we'll see it in the near future.
