>* the performance per watt of the most efficient supercomputer (7 GFlops/watt) vs the human brain (38 petaflops / 20 watts = 1.9 petaflops per watt) Encouraging, but AI wouldn't be constrained to an energy budget similar to a human. At the rates you describe, beating a human would take the output of only a single wind turbine. https://en.m.wikipedia.org/wiki/Orders_of_magnitude_(power) https://en.m.wikipedia.org/wiki/Orders_of_magnitude_(power)
