As of this book going to print, even ChatGPT, the famous chatbot released by OpenAI, does not continually learn from the millions of people who speak to it. It too stopped learning the moment it was released into the world. These systems are not allowed to learn new things because of the risk that they will forget old things (or learn the wrong things). So modern AI systems are frozen in time, their parameters locked down; they are allowed to be updated only when retrained from scratch with humans meticulously monitoring their performance on all the relevant tasks.
