I absolutely agree. All of those exist and there is less than this arbitrary 0.57 novelty rating there. Though I have to say that having studied together with MBA students their ideas were on the same level of uselessness. One did tell us in a seminar he had a great idea: What if you could pay with your phone for renting a car at the car you want to use?

Crass idea, back then there were already the first companies who rolled out that thing. He was convinced that his idea would make him money, not getting how capital is what makes you able to profit from ideas in capitalism.
