I think a lot of interesting points have been made in this discussion. It's complicated to critique creative expression/ music/ performance without seeming to be elitist and cruel, but without this discourse we would not be able to differentiate between true ingenuity and derivative mediocrity.
Mainstream platforms for "innovation" like TED invariably showcase "thinly" not "deeply" because they are all about wow-factor and soundbites, speaking to the most general of audiences. We could look at TED as a kind of media "iceberg". The ideas showcased may often be interesting but the substance of their presentation is often lacking, like the proverbial tip of the iceberg. So we should use these iceberg tips as a jumping off points to look deeper into the idea presented with our own research. Then we may (hopefully) find more interesting applications of similar ideas, for e.g. as in this case: gestural sound control.
