I don't think it's a counterargument, it's more a prediction for the late-game of manufacturing technology. For the mid-game, I suspect it will be like it's with chemistry, agriculture, pharmaceuticals and biotechnology nowadays - there is no unified sector encompassing all the areas above, but there are big companies, like Monsanto, 3M or DuPoint, doing all four at once, exploiting the relative similarities of the fields.
