There is, to me, and absurd amount of AI doomsday nonsense. I've been addressing some of it, but this recent article by Marc Andreessen summarizes my thoughts. Here is one excerpt regarding AI somehow exterminating humanity:
AI is not a living being that has been primed by billions of years of evolution to participate in the battle for the survival of the fittest, as animals are, and as we are. It is math – code – computers, built by people, owned by people, used by people, controlled by people. The idea that it will at some point develop a mind of its own and decide that it has motivations that lead it to try to kill us is a superstitious handwave.
In short, AI doesn’t want, it doesn’t have goals, it doesn’t want to kill you, because it’s not alive. And AI is a machine – is not going to come alive any more than your toaster will.
