Shannon's Limit

In the eighties, IIT taught a science of Communications, the "newest science", rooted solely in Shannon's Theory of Communication. He wrote that seminal paper when he was employed by Bell Labs. It's to do with clarity of transmission, and the distortion caused between sender and receiver.

With both turbo code and a three bit detecting code, plus an interwoven periodic bit, the engineers are now approaching Shannon's limit.

Does that imply that the science, which deals with human communication, could find that coding inserted by sender and decoded by two receivers will clarify human messages?
