I think that you are under estimating the potential and complexities of the human body and the human mind. Why do you and so many others think that we can create in 5000(giving the benefit of the doubt) years of improvement what nature made in millions of years of improvement? Our mind keeps track of an almost infinite amount of cells/neurons/movements/actions/thoughts in an incredibly complex mechanism that we barely understand. My body can actually defend and recover and replace many vital parts without my conscious work. And when i take medication to supplement what my body does, there are lists of problems that it causes at the same time. My computer brakes down and needs serous and expensive repairs in a 3-5 year window. I keep my information spread out across many computers in case i lose it to a bad hard drive or something brakes down. Do you believe that in only 41 years robots will be able to do all of that?

Don't get me wrong, I want to have a house robot to help me clean, garden, cook, and serve guests intelligently and smoothly. But I expect that I will have to have a repair man over to fix it, and I expect that I have it sell itself on craigslist and order a replacement every 3-5 years. And it is a good reason to get rich now.
