There's a myth that generally wars are good at rapid scientific process but that's just bias. They focus exclusively on the highly publicised (after later being declassified) advancements made during the war for the purpose of the war and totally forget about; all the progress that would've happened anyway, the millions of dead potential scientists and the things they'd have discovered, and the non-headline grabbing progress that forms the vast vast majority of scientific progress.
Overall big wars deprive us of gargantuan amounts of man-hours in virtually all fields of science.
