Imagine a super-duper smart robot brain that has read all the books and heard all the conversations in the whole wide world! When you talk to it, like saying “What’s blue and flies?”, it doesn’t really know what blue means, but it’s really good at guessing what word usually comes next after those words, because it’s seen it so many times. It’s like a fantastic guesser! It just tries to put words together in a way that makes sense and sounds like something a person would say....
