But before we start talking about hell we should be aware that the world has become so much safer and better the last 100 years. If a robots takes over we won't be able to stop it anyway. So live and enjoy life. It has become so much better!
You can't prepare against AI intelligence. It's too smart. And you can't educate people since we don't even know what an AI machine would be like. Robots have up to this point proven to be very reliable and friendly to us. It's humans that has started wars the last thousands of years not robots. I'm sure we can let the robots walk away.
If it happens it will either be more amazing or hell on earth. We are about to find out in the near future. I trust in evolution if it wants an AI then it will give that to earth.
You believe in fate?
