    Say the fyookball-1000 mining rig (a fictional machine) gives you 1TH and runs at 1000w.  Now the fyookball-2000 comes out and gives you 2TH but runs at 100w.  Well, now you doubled the hash but cut the electric bill. By 90%.  

    If every miner owned 1 FB1000 and suddenly replaced with the FB2000 , each miner would be making the same when the difficulty changes anyway.....but the power consumption is down.

    Except why buy 2 why not buy 10 and make even more money ?  If it is profitable to deploy 2 it is profitable to deploy 10 and people will.  They will keep deploying more and more and more hashing power and until the ROI is right back down to that low level it was before the more efficient hardware came along.

    This is the same as ANY commodity business.

    Yeah but the thing is the rig is the main cost not the electricity...at least for now.

    Well "main" cost is kinda subjective.  At $1 per GH/s and 1 J/GH energy is pretty close to half the cost.  Margins are still high on hardware so expect hardware prices to fall much faster than energy costs and that will shift more and more towards energy.  Still it is a pointless distinction.   Miner total cost is amortized hardware + energy costs.   If the network gives miners $500M annually then miners are going to spend pretty close to $500M annually as they collectively drive the margin very close to zero (possibly negative).   It doesn't matter how efficient the tech is, miners will simply buy and deploy more gear until margins are so low (or negative) that deploying more hardware doesn't make sense.

    Once again we have been seeing this continually for five years so it isn't some academic theory.   It is a classic prisoner dilema.  Sure if there is new technology and miners agree to limit the hashrate of the network then they can increase their margins but they can't and if they tried someone would cheat to make more while the margins are higher.  Economics will drive hashrate up and margins down when more efficient tech is possible.
