I think we'd be much further along if we kept our wet ware and learned how to program our existing DNA and proteins. We already have a functioning system that does what we want and a whole planet full of example code. The molecular machines even do all the work for you if you give them the right instructions. How happy would you be if I offered you functional nano technology capable of producing self sustaining macro structures from elements and energy scavenged from the environment? It's literally under our noses and almost nobody has noticed.
