I think one of the biggest things that can happen, and people have been talking about this today, is that human beings of course are very clever, or so we like to think, but there is a chance that robots and computers will help us not only answer the questions we pose, but will help us pose some of the questions. And that is one of the big hopes in a way, for this mess that we have made on planet earth. Thus hopefully we can get to the point where computers and robots will help us, if they don't kill us!
