Other than being annoying, what are the arguments for permitting AI to hold patents? Why does anyone want their AI as opposed to their shoelaces holding a patent? I don't get it. Seems like the only purpose is to cause legislation preventing it, which is fine, but what are the problems and benefits of an AI holding patents? Is the purpose merely to politically advance AI, re: nutty affectation, or to prevent the same? Again, but why?
