Japan tried to build an operating system for the entire world, then the US government intervened

And once upon a time there were more than three PC graphics card makers. The paranoid schizo US really fucked up scientific and technological progress.

They rose to the top because they were the only country that could still build things after the rest of the world got flattened in World War II. Then the rest of the world rebuilt itself so the only asset the US had left was economic inertia. They then proceeded to spend decades doing everything they could to increase the value of that inertia by using their influence to encourage policies that resulted the rich getting richer.
