MIT professor Neil Gershenfeld gave a provocative talk last night at the Future Salon on personal fabrication and digital-physical interfaces. He has set up fabrication labs all around the world, and you will be suprised at the results. Gershenfeld envisions a not-to-distance future in which individuals or communities have the ability to fabricate materials and goods at the nano-scale. Rather than receiving a package in the mail, the design can be emailed to you, and the item created in your home. Or better yet, you will design it yourself, and email the design to your friends. This could lead to a new paradigm of open-source hardware, and a shifting notion of materialism and consumerism. How this will affect the digital divide is unknown - it remains to be seen whether the emergence of this technology will lead to a ‘fab lab in everyone’s home.’ Gershenfeld also has some interesting ideas regarding venture capital and microfinance.
