In the US, (nearly) full electrification wasn't achieved until the late 1940's/early 1950's - a process of nearly a century. (A moment of personal trivia, my great grandfather worked on crews electrifying rural areas of the midwest.)
What comparable gap is there to bridge?
Energy costs vary widely across the world and that has enormous capacity for the economies of different countries and their industrial capacity.
Electricity looks pretty even. Higher in Europe but they can afford that.
(And the profit from selling GPUs isn't haves versus have nots, it's a couple companies versus the entire world.)
