Flying cars have long been a symbol of the possible technological height of human transportation. But we're not exactly surprised by their absence. Similarly, can't Drexler's '90s idealism be regarded as the possible peak of nanotech? Does the fact we don't have tiny toasters in our bloodstream really negate the acheivement of nanotechnology in medicine and materials science? Personally, I don't think so. This article is too deliberately inflammatory, and doesn't properly look into anything beyond what is now an ancient thesis - as far as fast-moving research areas are concerned. This makes his dismissal of nanotech as sweeping as Drexler's predictions.
