Warner Bros. was already investing in sound. Harry Warner believed that the sound that would sell movies was music, not prose. His mistake was artistic, not technological." http://www.usatoday.com/tech/columnist/kevinmaney/2005-07-05... Jack Warner was talking about "The Jazz Singer" which his company was releasing. Again - a little knowledge is a dangerous thing. "uppose you wanted to make a superior sword. Can you imagine a day when a 3d printer can arrange each particle of material to achieve optimal atomic arrangement of iron and carbon to create something far superior to something that can be created by the world's greatest craftsman?" No. Because, you see, I had to take two five credit courses in steel to get my degree and I know it doesn't work that way. You make steel strong by working it. And, if I can make steel strong by working it, I can make things a hell of a lot cheaper than "printing" a sword molecule by molecule. 'cuz that's the thing - cold forged steel, hot forged steel, machined steel and cast steel are all very, very different things, above and beyond what's in the steel. And I can control that stuff with '20s era technology. The article is talking about 3d printing. You're talking about Star Trek-style replicators. There's a difference.
