Why Do A.I. Chatbots Tell Lies and Act Weird? Look in the Mirror. - The New York Times

As it analyzes that sea of good and bad information from across the internet, an L.L.M. learns to do one particular thing: guess the next word in a sequence of words. It operates like a giant version of the autocomplete technology that suggests the next word as you type out an email or an instant message on your smartphone. Given the sequence "Tom Cruise is a ____," it might guess "actor." When you chat with a chatbot, the bot is not just drawing on everything it has learned from the internet. It is drawing on everything you have said to it and everything it has said back.
