Watching this, I thought this was pretty far-fetched stuff. Creating human skin in 3-D form that could be used to replace body parts? Come on, who do they think they are kidding? That stuff is decades off. Then I came across this video about printing body parts. An earlier post on programmable matter touched on the idea of 3-D printers making coffee cups. Here we have a printer that uses human cells as its ink to fashion ears and other useful spare parts.
Like it or not, the future is coming at us fast. A world we can hardly imagine is taking shape right before our eyes. We push up against the barrier that separates us from the gods, a barrier that is far more permeable than we might ever have imagined. Are we ready for this? God only knows.
