Yes, that's the point.

While buying a stereo system component, James Lileks observed: "A manager had to be called to cancel the transaction, and as the fellow deftly entered in a series of codes I wondered how many skills exist today that cannot be transferred from one job to another. Once upon a time, you made barrels for one guy, you could make barrels for another. But the moment you leave BestBuy, your knowledge of their point-of-sale codes is useless. You can transfer the ability to learn, but not the thing you actually learned. In the end it’s your ability to master the system that’s the skill, I suppose. " (Emphasis added.)

Yes, exactly.
