You're splitting hairs. Yes, technically knowledgeable and capable people are still in demand but on average the trend that the OP is mentioning is quite true. And due to human limitations one cannot go both in depth and breadth. And with the proliferation of technologies and the rapid pace of cycles and recycles, the ones who keep up with the trend are more likely to be better rewarded.

That requires operating costs to have been 10x in the first place right? It doesn't do you much good if you kept them low from the beginning.
