Oh I love this. Article on BBC about how robots are learning to talk to each other. Their big secret? Avoid using human language: it is too loaded with information to be of use so it is much more efficient for robots to develope their own language. Is this a little like English as a Lingua Franca? Will the Elves take over the world? Is it a devious plot so that when they have taken over the world we won’t even be able to argue back as we won’t speak the same language? Surely Asimov should have forseen this. What would happen if our students did the same, cut out the teacher and spoke amoung themselves … in fact that is what happens quite frequently when a native speaker faces a monolingual classroom. Then, as a result, it is the teacher who becomes robotic . More than just science fiction to think about here.
