I agree; that is part of his argument. Obviously though it is a completely flawed argument. Up until the creation of the personal computer most machines were specialists. They were large computers designed for specific computation tasks or machines made specifically for manufacturing certain kinds of goods. Generalist computers didn't have much precedent. That's kind of the point of new technology. It's not necessarily predicated by something that came before. It is orders of magnitude better.
To me this argument has historically less validity than creative people dreaming about singular, binary acts of creation. Historically those people have won.
