This is a shorter version of Goldhaber's full argument, from "The attention economy and the Net"[1]l, written for a popular audience. Goldhaber wasn't saying that money won't be real, but that there will be those who can command attention in ways that are, but need not be, convertible to money in the ordinary sense. It's definitely a driver behind ad-supported Internet services and mobile devices. The companies working off this are converting the attention of their users, enticed by clickbait or algorithmically-generated recommendations, to audiences delivered to advertisers and sellers, who then exchange money for the attention brought to them.
