I said that somewhat tongue-in-cheek, but the line between "drone" and "missile" seems to have gotten pretty blurry with the Ukraine war featuring FPV drones holding a hand grenade that are effectively a human-piloted missile.
Some modern missiles can fly around to identify targets, but they can't return home. They can blow up harmlessly if nothing is a target, though. They can also dodge and weave the way FPV pilots do.
Obviously, "drone" has a much more expansive mission profile than "missile."
