I was for the change PoW to something more ASIC-resistant until I recalled old LTB podast about the same issue on the bitcoin network. TLRD: it will be always about whoever is ready to dump more $$$ to buy hashpower. It doesn't depend of the source of hashpower, be it CPU, GPU, ASICs or pigeons.
So the real issue is the decentralization. And it will increase with dropping cost per mining unit and raising perceived effectiveness of mining operations.
Thus changed my vote to "neutral"
