    I don’t think you understand exactly how theses machines work. The machine does not “learn”, it does not extract meaning from the tokens it receives. Here is one way to look at it

    Suppose you have a sequence of symbols: ¹§ŋ¹§ŋ¹§ŋ¹§ŋ And then were given a fragment of a sequence and asked to guess what you be the most likely symbol to follow it: ¹§ Think you could do it? I’m sure you would have no trouble solving this example. But could you make a machine that could reliably accomplish this task, regardless of the sequence of symbols and regardless of the fragment given? Let’s imagine you did manage to create such a marvellous machine.

    If given a large sequence of symbols spanning multiple books of length would you say this pattern recognition machine is able to create anything original? No… Because it is simply trying to copy it’s original sequence as closely as possible.

    Another question: Would this machine ever derive meaning from this symbols? No… How could it?

    But what if I told you that these symbols weren’t just symbols: Unbeknownst to the machine each one of this symbols actually represents a word. Behold: ChatGPT.

    This is basically the general idea behind generative AI as far as I’m aware. Please correct me if I’m wrong. This is obviously oversimplified.

      Yeah, all training ends up being pattern learning in some form or fashion. But acceptable patterns end up matching logic. So for example if you ask ChatGPT a question, it will use its learned pattern to provide its estimate of the correct ouptut. That pattern it’s learned encompasses/matches logical processing of the user input and the output that it’s been trained to see as acceptable output. So with enough training, it should and does go from simple memorization of individual examples to learning these broad acceptable rules, like logic (or a pattern that matches logical rules and “understanding of language”) so that it can provide acceptable responses to situations that it hasn’t seen in training. And because of this pattern learning and prediction nature of how it works, it often “hallucinates” information like citations (creating a novel citation matching the pattern its seen instead of the exact citation that you want, where you actually want memorized information) that you might ask of it as sources for what its telling you.
