Are quadcopters / multirotors drones?

I want to talk about why I like drones, what their best features are and where I see it all going.
In order to do that though, we're first going to have to define 'drone'. Everyone seems to hear that word and think of different things. So, to me, drone means a flying vehicle that has some level of autonomy. That is an ability to control, at least part of, their flight with no human input. So are most toy RC planes also drones? No, almost always not. They're controlled by simple electronics, responding to inputs from the transmitter and moving a control surface accordingly. Most toy planes don't even have gyros.
What about the predator and reaper drones that we hear about, flying over the middle east. Would I say they're drones? Yes, of course I would. They are able to loiter in the air for hours and follow GPS coordinates with little to no human input.
But, this blog isn't to talk about those kind of drones. This blog is for multirotors so, the question that everyone seems to answer differently, are multirotors drones? Yes. In my opinion, 100%. Unlike a toy RC plane, multirotors have 'brains' (so to speak) they're not dumbly following human command with no input from their own decisions. Most flight controllers for multirotors are capable of auto-level flight, using their onboard gyros to tell them what is up or down. They will spin up or down specific motors in order to maintain this level flight with no input from people and, in my opinion, this is autonomy. Even in rate mode, where there is no auto-level function enabled, the multirotor still calculates how to control each of its motors to produce the response the pilot is after. In other words, because multirotor pilots are not controlling each motor themselves, spinning each up and down as necessary, they are not the only 'brain' flying the vehicle. To me at least, this makes them drones.
