The lead character in the fourth Dune book, God Emperor of Dune, had a technology that was wirelessly tapped into his brain. And during his 3000 year reign of the universe, whatever thought he had was recorded somewhere in some archive. All he had to do is consciously think it and it was written down.
There are times I wish I had this technology. Many times I've had ideas that I wanted to write down or even blog about here, but I'm usually not in a position to get it added before the thought is gone.
I'm sure the idea for the technology came about from the author of the book, Frank Herbert. He was a thinker and probably wished, like me, he had the technology to provide the service.
