I think you're going to be right, but not yet. Today we can make complex atomically-precise structures and machines with http://en.wikipedia.org/wiki/DNA_nanotechnology http://en.wikipedia.org/wiki/DNA_nanotechnology but DNA is weak and floppy. There's much left to do to bootstrap to stronger stiffer systems that are easier to design.
