You have simplistic idea of what an invention is. You see it as something that must be created in a vacuum and if it has any aspect of it from the past it’s simply an “evolution”. The telephone wasn’t an invention because the telegraph existed before it. “It’s all just stuff going over wires”, you would say. The television wasn’t an invention because the radio existed beforehand. “It’s just stuff being broadcast over the air, they’re practically the same thing”, you would say. The airplane wasn’t an invention because hot air balloons and blimps already existed. “It’s just stuff flying through the air, the hot air balloon did it first, they’re just copying that”, you would say. The automobile wasn’t an invention because carriages and buggies were around first. “They’re just replacing the horse with an engine”. Additionally, you would claim automobiles weren’t the first things to have wheels, seats and windows as parts. The automobile is simply an evolution the of the house and human pulled flatbeds, you would claim.
I guess that leaves us with what? Silly Putty?
