I don't think that's necessarily the case at all. I think that at every step along this way, whether it’s every six months or every year, we're not even measuring in terms of time but measuring in terms of technologies and innovations that appear, we're constantly thinking about: Are we harnessing it or is it harnessing us? This is an iterative process. We're not jumping from now to the singularity. I believe there will be many controls along the way. There will be many successes and failures in experimenting with managing technologies, and as a result I don’t believe that we're ever going to reach a situation where it controls us. I don’t think that will ever happen.
