I mean… yeah, DARPA will probably be one of the first adopters of that stuff, it’s true. But DARPA is pretty much always a first adopter of any new tech, because they’re basically the research wing of the US military, and they have effectively infinite resources at their disposal (note: I am not debating whether or not that is a good thing here; simply stating that it is a thing). But just because they’ll likely do something military-ish with it first doesn’t mean that it’s a “bad” technology. The internet itself was, after all, initially a project of DARPA’s predecessor, ARPA, and was initially named “ARPAnet”.
