Re: You do not realize how old a movie is... If you're going to use that argument, all discoveries are just extending the use of something already available. AC power always existed. Nuclear reactions always existed. Radio-frequency radiation always existed. It merely took someone to figure out how they work and harness their potential for practical purposes.
So, knowing this, your claim either isn't valid, or it's a blanket statement that applies to everyone at all points in history for all discoveries. Take your pick.
