I would put it as follows: in the last 30 years there have been real advances in practical nanotechnology.
Not Drexlerian nanomachine fantasies, but nanometre scale control of the surface geometry of materials. Controlling surface geometries at these small scales is what has powered the advance of solar PV since 1990.
This would not have been possible without the continually increasing computer simulation power that has been available since the 1990s.
