Speak only of your own willful ignorance. Nobody said anything about inefficiency; ASICs are extremely efficient at wasting energy. The point that Bitcoin proponents refuse to admit is that, unlike other systems, making the components more efficient does not reduce the energy consumption of the system, because energy consumption is the purpose of this system.
Even worse, it puts a floor on the price of energy, which disincentives everyone else from seeking more efficient solutions to power production, because all that efficiency will be wasted by proof-of-work anyway. We as a species will never have free energy, and this is the reason.
