The years you cite are when drone tech was developed and deployed in combat, and cryptography improved. The DoD funds all kinds of research through the university system that isn't public, you may have no idea what it brought us because it's too recent. The DoD is funding all kinds of projects today, despite our capitalist tendencies, for example: https://www.defense.gov/News/Releases/Release/Article/309821...
I don't know what you mean about Starlink being marketing. They've deployed more satellites than all other satellites to date combined. You said you thought a project this size wasn't doable today, yet there it is. It seems like you're arbitrarily judging what projects you believe are worthy of consideration in order to support a preconceived notion. Why do you believe GPS involved more invention or development than Starlink, drones, cryptography, machine learning, or anything else? GPS technology was also developed before the US Navstar project began, the science already existed and it wasn't some kind of lone independent invention.
