Shannon is such an engineering marvel as Einstein is for science. His perennial works, hobbies, papers and theses outlined the fundamentals of modern engineering foundations including digital, computer and communication systems including AI systems of early forms of chess engine, LLM, etc [1]. Kleinrock once noted that he has to pursue exotic field of queuing theory that led to packet switching and then Internet, because most of popular problems in his research field have been solved by Shannon (who was also one of Kleinrock's doctoral research study committee members).
