Agreed. I'd be a lot more impressed if they trusted it enough to carry a real payload and didn't just fly it by remote control. I believe we now have engine technology with a power-to-weight ratio that would make a quad rotor capable of lifting a human possible, but the power is pretty close to the edge and the control systems are difficult to make safe. So it is theoretically possible to make one, but since it would cost about $100 million to develop and the liability issues would prevent you from ever getting any return on investment, nobody is going to do it.
