Replicating machine will be invented

Arthur C. Clarke : science fiction author, inventor, and futurist
“Replicator is simply a duplicating machine, but it is a duplicating machine which can make an exact copy of anything. We all are pretty familiar with perfect copies of printing, of pictures and of sounds, yet the camera and the tape recorder would have seen miraculous to our (aunt sisters?) and to any of the monk who perhaps in all his life only saw a few dozen of a books each one patiently copied by hand. Our present world in which literally million books exists will again have seen absolutely inconceivable. Can we imagine the world in which objects can be made as easily as today we can make books. Well, don’t ask me exactly how the replicator will work. If I knew I will patent it at once.”
