Moore's law on ASIC limits, impact of mining, halving etc... thoughts ?

So we are at 7 nm ASIC chips currently before we would do 20-50-100x over the last years in terms of expanding technology and efficiency with ASIC. But if you follow the curve we are almost at the end of that practice... it is not physically possible to get 20x-50x-100x in ASIC efficiency like before, so the solution would be only to stack more chips right? then again there is power consumption that we can work on, but then again that has limits also, so are we going to get stuck with super-efficient ASIC chips that can squeeze only a few % to get better over the course of next decade? and the only solution would be stacking chips and trying to get better electric efficiency? that was not a problem to consider before so much as it is now, that many people don't think about.​We have XY amount of "Hash Power" now with every halving block reward cuts in half, that will trow many miners out of the game if ofc price doesn't increase dramatically... so more and more people want to mine but the game is much much harder, you have to invest in stacks and stacks of ASIC chips that reached almost their physical limits, in theory. I don't think people understand the importance of this and how much big impact will this have on price when miners quit more miners jump in because the network is easier and that create an opportunity for more BTC when more miners are in-game you get it... what are your thoughts about all this now? via /r/Bitcoin http://bit.ly/2IfqUR4
