Ultimately, the only people who benefit from ASIC mining are the manufacturers of ASICs. They are effectively taking a big chunk out of the zero-sum game of cryptocurrency mining and giving nothing in return.
ASIC manufacturers and their close accomplices who are able to buy bulk amounts of these at discounted prices. Everything is so much more profitable when things are done at scale. The beauty of mining is that time to 100% ROI is the same whether you invest on 1 GPU / ASIC or 1,000,000 GPUs / ASICs.
Imagine how happy those early miners who invested in 100+ GPU rigs are.
