A lot of our nanotech is still in the micro domain or dealing purely with chemicals. A CPU's fundamental organization is too small to be seen without a really, really good microscope, nanomedicines currently only deal with germs and minor changes to their environment, and so on. We have yet to touch the macro domain. For example, nobody has built a car body out of carbon nanotubes so far, and just imagine what would happen if someone found a way to make photovoltaic cells self-assemble on boards dipped in a vat.
