Thought experiment: To be truly "original" a child that grew up with wolves in the jungle would have to come up with it (okay, not even that since it learns from the wolves). Everything else is "not truly original". Duh.
Now that we have established that no truly "original" ideas exist in any human's head (assuming "original" means going from totally empty, nothingness, to the idea), can we just get rid of all comments pointing out that X didn't really invent Y but was inspired by P?
Of course, what I just wrote isn't original in the slightest, I just don't know the names of all the people who said it before.
