Ed note: More on Wurman and why he thinks TED is so last century.
TED’s notion of “ideas worth spreading” — the implication being that spreading is itself a work of hierarchy and curation — has its origins in a print-based world of bylines and copyrights. It insists that ideas are, in the digital world, what they have been in the analog: packagable and ownable and claimable.
A TED talk, at this point, is the cultural equivalent of a patent: a private claim to a public concept. With the speaker, himself, becoming the manifestation of the idea. And so: In the name of spreading a concept, the talk ends up narrowing it. Pariser’s filter bubble. Anderson’s long tail. We talk often about the need for narrative in making abstract concepts relatable and impactful to mass audiences; what TED has done so elegantly, though, is to replace narrative in that equation with personality. The relatable idea, TED insists, is the personal idea. It is the performative idea. It is the idea that strides onstage and into a spotlight, ready to become a star.
