Na konferenciji TEDGlobal 2010, autor Matt Ridley pokazuje kako je, kroz povijest, motor ljudskog napretka  sretanje i parenje ideja kako bi nastale nove ideje. Nije važno koliko su pametni pojedinci, kaže on; ono što je zaista bitno jest koliko je pametan kolektivni mozak.

Matt Ridley: Kada se ideje poseksaju

Prosperity has soared not because of lone geniuses, but because people exchange and combine ideas. Over the past fifty years, global income has tripled and child mortality has plummeted, even as the population doubled. Trade, specialization, and collective innovation allow humanity to achieve things no individual could create alone. The true engine of advancement is the shared 'collective brain' that grows as more people contribute and connect.

Human Progress Thrives When Ideas Connect and Multiply
