• Peter Thiel's philanthropic foundation has invested in Modern Meadow -- a company that will develop 3D bioprinting techniques for disrupting the current meat industry. Growing edible meat tissue without a farm could be more environmentally friendly, but one of the company's first goals is to just grow a 1-inch long piece of synthetic meat suitable for eating. [url]
• Cornell University has a food printing lab as part of its Fab@Home venture. This group has been working on printing food since 2007, and the researchers speculate that food printers could vastly reduce the time people spend preparing food. [url]
• Burritob0t is an open source project to create a Tex-Mex 3D printer, capable of generating tasty, custom burritos from extruding ingredients such as beans, rice, cheese and salsa onto a tortilla. Unfortunately, lettuce and chunky salsa aren't on this robot's menu -- but perhaps a meat paste could be added... [url]
• Chocolate lovers in the UK might want to thank researchers at the University of Exeter for creating a 3D printer that prints layers of chocolate. These developers want to create a website that anyone can print chocolate creations from -- but they'll probably need a really good Spam filter before they turn that feature on. [url]

A better analogy would be if the replicator only made tomatoes. You could have as many tomatoes as you wanted, they'd always be perfect and delicious, and they'd always be free. This would put tomato farmers out of business. But these tomato farmers could likely start growing something else instead. And what happens to the rest of the economy? Pizza and pasta restaurants suddenly find that a major ingredient in many of their dishes just became free. Now, for the same dish, they can charge less, or buy higher quality ingredients, or make more profit. And if you're a really talented cook specializing in tomatoes? Your skills are now in very high demand.

And there is still a demand for the people who bring the tomatoes from the replicator to your table. There is still a demand for the person who stews and cans the tomatoes, or dices and seasons them. And all the other food items, the ones that aren't in infitnite supply, still need people to produce, process, and distribute them.

This is what's happening in the music industry, and starting to happen in the publishing industry. Some parts of the industries are finding their functions obsolete. Instead of looking at the money they could save with electronic distribution, and what good use they could put that money to, the industry is seeking new laws and regulations to limit the infinite supply so business can continue as usual.

Even if every single song, book, and movie was distributed digitally for free, there would still be a need for the music, publishing, and movie industries. There would still be demand for editors, producers, marketers, and all sorts of other services that these industries have always provided.

Reasonable people aren't calling for the abolition of the music, publishing, and movie industries. They're just asking these industries to look to the future, and stop trying to limit supply to protect obsolete business models.
