Of course, like literally every other time this has played out in computing history, the companies focused on price performance will end up with more economic resources, and get to turn the upgrade crank more often and for longer.
Also, of course, China's way ahead of the US on things like renewables, batteries, and electrification of their economy. All of that feeds into cheaper power to run the models, but I suspect it's a second order effect vs. "improve the software".
