Exactly. Seeing this and saying: "These are just helicopters, but smaller" isn't very helpful. The big difference between these and "real" helicopters (either realsize ones or RC helicopters) is that now these things are using a super fast feedback loop to find their balance. This could definitely one day help piloting real helicopters: just like these feedback-looped quadcopters are way easier to fly than the RC copters...
