Large Language Models aren’t AI, they’re closer to “predictive text”, like that game where you make sentences by choosing the first word from your phone’s autocorrect:

“The word you want the word you like and then the next sentence you choose to read the next sentence from your phone’s keyboard”.

Sometimes it almost seems like there could be an intelligence behind it, but it’s really just word association.

All this “training” data provides is a “better” or “more plausible” method of predicting which words to string together to appear to make a useful sentence.
