I think his point isn’t that it is trivial, just possible. Off the shelf tools exist and practitioners (of which there are thousands) can build solutions now to identify tanks or people on a kill list, or whatever the military wants.

DARPA looks at what is plausible and spends money to get the brainpower (a number in the hundreds or less) who can create the tools and create the process thinking about things that the military wants or needs.
