What would happen when every one would have access to Internet? How different will the world be when everyone carries a computer in their pocket? Can communicate with anyone regardless of location and language, with no intermediary? Those were questions we used to ask ourselves not so long ago. Turned out: not much have changed.
For the future to be evenly distributed, much bigger changes will have to happen than large scale manufacture of efficient GPUs. Otherwise, tech will just be used to make sure progress and knowledge stays unevently distributed. That's the whole game of herding humans, after all; It's called "organized scarcity".
