"In 1834, the first working vapor-compression refrigeration system was built." - that is not a derivative of cooling food by putting it on a block of ice brought from Canada. I'm not doing No True Scotsman because that is a true scotsman. Before it you couldn't chill things on demand below what the weather was doing, for any price. After it, you could. A breakthrough from a world where cooling was down to ice and luck, to a world where control of cooling, pumping heat, is a thing. By saying everything is innovative, you're making no distinctions - if everything is, nothing is.
