Innovation. Electric light bulb (contrary to Biden's claim that Lewis Latimer, a black man, invented the light bulb...he invented a better light bulb filament, along with a cohort), phonograph, camera, movies, telephone, telegraph, radio, air-conditioning, refrigeration, automobile, airplane, rockets, tanks, firearms, personal computers, internet, et cetera, et cetera, et cetera.
None of this isn't to say that there weren't blacks behind the scenes in some of these cases, assisting (think the movie, Hidden Figures, the black women were instrumental in the mathematical extrapolations, getting the Apollo program going....but it was a joint operation).
This also doesn't diminish the inventions/creations by blacks. But it's the whites, like it or not, that excelled at innovative inventions.
