"It is easier to read a book than to write one; easier to listen to a song than to compose one; easier to attend a play than to produce one. But movies in particular suffer from this user asymmetry. The intensely collaborative work needed to coddle chemically treated film and paste together its strips into movies meant that it was vastly easier to watch a movie than to make one.
A Hollywood blockbuster can take a million person-hours to produce and only two hours to consume. But now, cheap and universal tools of creation (megapixel phone cameras, Photoshop, iMovie) are quickly reducing the effort needed to create moving images. To the utter bafflement of the experts who confidently claimed that viewers would never rise from their reclining passivity, tens of millions of people have in recent years spent uncountable hours making movies of their own design."
