This is how all tech works - trains, cars, power stations. We build things that are initially inefficient. We eventually transition to energy efficient tech. We celebrate. It’s rare the transition can reduce 99.95% of energy footprint the size of a country within a minute of activating the new tech.

The difference is that PoW is not "inefficient". Rather, it is intrinsically wasteful by its very nature.

Take an inefficient car for instance. There are diminishing returns in its utility after a certain point of energy use. On the other hand, there are no diminishing returns in PoW. The more energy you use, the more money you make.

Sure? It was both an inefficient and wasteful mechanism to secure consensus. This is why developers have been actively researching and developing how to switch Eth to PoS for years.

An electric heater runs current through a wire .. the waste product of doing so is heat. The more you 'waste' the more heat produced.

I guess the more efficient version of the same thing would be the move to using heat pumps.

Trains, cars and power stations serve a purpose. The blockchain only creates waste with nothing in return. Yeah it does pollute less now, but it's still too much.
