I think quadcopter construction is a joke. Very cute, but not serious. Despite having awesome computers and software for decades, construction costs are not going down. While some technology can be very helpful (cheap walkie-talkies are a boon to constructing a large building quickly), they haven't change the cost curve dramatically.
