Even if the acceptable price consumers are willing to pay for content approaches zero, that hardly means the value of content approaches zero. To the contrary, if you're able to search vast amounts of content for what is most interesting to you, the value you receive from that content increases with the size of the search space. It's a clear win for the audience.
But what about the content producers? Already, most "real book" authors don't publish to get rich from royalties, and derive most of their value in the form of personal and professional publicity they receive from their work. If the acquisition of such publicity shifts from big corporate publishing houses who have the business deals in place to get you on The Daily Show to something more democratic, authors benefit from an increasingly meritocratic system, as well.
