I don't know if I agree with this statement. If one of the main goals of the fascist state is technological superiority, they'll prioritize it. Nazi Germany was on the cutting edge of science, to the point that the US hired a bunch of their scientists. They made technology a priority at the expense of other sectors. Luckily, being incapable of trade or producing the resources they needed, they didn't outstrip the rest of the world, but the same likely can't be said for the US. I think other factors will get in the way of tech research in the US far more than fascism, like moronic trade wars and disincentives for higher education, which while being enacted by fascists, aren't necessarily fascist tenets, as proven by history.
