TED Talk ; Can we make things that make themselves?

With our current technology we can manufacture a sky scraper within two and a half year that are made up of up to one million part. Yet we are not as efficient as many basic natural manufacturing systems such as in DNA replication which consists of three million parts yet can replicate in only and hour. What is even more intriguing about natural systems compared to artificial systems is that natural systems rarely commit errors. Through all the complexity natural systems are also able to repair themselves. This is where are future technology is should begin to deviate. We should decode the complexity of what we hope to build, we must create programmable parts that are able to reconfigure, we must have a source of energy to allow our system to be functional and we must create an error correction system of some sort to be able to create exactly what we want. With this new technology we can make things that simply make themselves.
