Parent was presumably leaving unsaid "... at scale", aka enough to move a chunk of the hash power.

Thanks yes I totally meant scale. Main cost of new ASIC chips is design and fabrication. Only serve a very narrow specific purpose and all that cost is sunk. But after that, unit production chip cost is negligible.

do you happen to know b/e costs given difficulty/profitability ratio using current market electricity prices?
