Interesting: I thought that Edsger Dijkstra's reference to the submarines were that of "The threats to computing science" ( https://www.cs.utexas.edu/users/EWD/transcriptions/EWD08xx/EWD898.html https://www.cs.utexas.edu/users/EWD/transcriptions/EWD08xx/E... ), earlier, of 1984 - where he mentioned it in the context of the initial uncertainty of the scope of Computer Science, with reference to Turing's question "Can Machines Think?": > The Fathers of the field had been pretty confusing: John von Neumann speculated about computers and the human brain in analogies sufficiently wild to be worthy of a medieval thinker and Alan M. Turing thought about criteria to settle the question of whether Machines Can Think, a question of which we now know that it is about as relevant as the question of whether Submarines Can Swim But that next speech warns against anthropomorphism. It remains that we sometimes metaphors are useful. Only, we have to be normally wary not to jump outside the intersection (between described and description).
