Either way, don't deprecate the flesh. It'll be a long time before technology, nano-scale or otherwise, can surpass the capability, functionality, and ruggedness of biology.
Indeed, some of the most promising cutting-edge research in computer technology involves using neural matter or DNA. I think that instead of technology replacing biology, the future will involve the two becoming increasingly interdependent and maybe eventually all but indistinguishable.
Yes, the end of the biohuman as we know it. Long live the new flesh.
