Neil Gershenfeld, Prof at MIT, was on Talk of the Nation Today talking about new machine tool technology. Gershenfeld teaches a course called How To Make (almost) Anything. He was talking about advances in computer controlled machine tools have dropped the prices to only about 20K. which is alot of money, but only half the cost of a truck.
There was some discussion of people being able to manufacture on demand for their own personal needs. Star Trek was mentioned in only to say that the technology for replicators are not here yet.
