Pfft, get real - Robinson R22 light broomstick choppers with muster pilots and crop dusting family STOLs make far more sense for their agility, ground hugging, and rough short take off / landing field capabilities.
That quibble aside, I can see things going that way, until flooding waves of many drones push up the human life cost past being able to respond.
Either way, they still need to be backed by some agile radar capabilities - variations of the E-7A Wedgetail design for ground and air to keep sensing on the hop.
