The problem is that if the DOD abandons the cutting edge in favor of systems they can produce quickly and cheaply, they will be ceding ground to the Chinese in one of the main advantages we have (the cutting edge). We aren't going to outproduce the CCP, so we need to stay ahead on the tech curve.
I think a huge existential question being asked is if living on the leading edge of aerospace technology is still paying dividends in manned aircraft. Maybe all those fancy features are over priced or else more effective/less expensive in unmanned platforms. You have to add a decade of forward thinking to any manned program, because that’s how long it takes to generate one.
