The future of Mankind

What is the future of mankind? Evolution never stops working, so we will be a more advanced design. In this case, we will build our inheritors, using a more intelligent brain than AI, physical muscles and much more. Why does SETI keep expecting to be contacted by organic creatures with six arms and five eyes. By the time that creatures can survive a journey of 200 years and fifty light years of space, they will not be organic but machine based. Paul explores the implications of these ideas.
