Energy consumption is an input, whereas GDP claims to be measuring an output, which is what the post concerns itself with. In principle you could have GDP growth while energy consumption drops if other inputs increase simultaneously.
So going back to the outputs: How much do you think the equivalent of a 2 GHz laptop with an internet connection would have cost / could have been sold for in 1960?
