To err is human. AI software modeled after humans will inevitably make mistakes. It is fine as long as the software learns from its errors and improves itself, which is something that humans ought to learn from AI. Aldous Huxley, author of Brave New World, wrote in "Case of Voluntary Ignorance" in Collected Essays (1959): "That men do not learn very much from the lessons of history is the most important of all the lessons that history has to teach."
