I just watched this TED talk by Nick Bostrom which is about what happens when computers get smarter than we are. It follows the theory that once we have created AI that is smarter than us, that AI will be able to create AI that is even smarter than itself. So at that point we’ll be left behind very quickly. Intelligence will develop a dynamic of self-improvement that can’t be stopped.
What he doesn’t realize is that we are already in that mode. We have already created people that are smarter than we used to be. And those people have created people who are smarter than themselves. That process has been going on for hundreds, if not thousands of years. The human brain is not the limit for human intelligence.
