I'm currently sat on a train beside a man who's been helping develop robot dogs. He was telling me all about how he's conducting research to develop their movements and has been telling me how the evolution of AI has been beneficial to his research. He was even showing me videos of a prototype. His aim is to get them to carry out complex tasks. Their initial application will be to survey potentially dangerous sites like building sites and nuclear plants. Anyway, it got me thinking. What other interesting stories do people on Reddit have to tell about people they've met on a train?
