It'd be interesting to see what'd happen if the military just pivoted into having top consumer electronics companies manufacture weapons using best-available current technology, perhaps designing them from scratch. The "peace dividend" from the end of the Cold War was literally spent on the Internet - my wife's father used to make guidance systems for SLBMs in Silicon Valley, now his son and son-in-law both work for Google. The rapid progress in software, networking, and electronics over the last 30 years is because a lot of the top engineering minds who otherwise would've gone into defense are now going into tech.

This is also what happened in WW2 - the bulk of the U.S. war machine wasn't built by the shipyards and artillery vendors that had supplied WW1, but by new consumer giants like GM, Chrysler, Raytheon, Boeing, Hewlett Packard, Fairchild that pivoted from consumer markets to the war, or defense-specific startups like Grumman & Kaiser that were founded in the 10 years leading up to the war to capitalize on new technologies. WW1 technology was generally obsolete by WW2; the war was fought in a fundamentally different way, with different suppliers, because tech had advanced.
