Yes, it is impossible. There are no "thoughts". The bloody thing doesn't know what an Apple is if you ask it to write a 500 page book about them. It just guesses a word, then from there guesses the next one and so on. That's why it will very often confidently tell you aggravating bullshit. It has no concept of the things it spits out. It's a "word calculator" so to speak. The whole thing is not "revolutionary" or "new" by any stretch. What is new is the ability to use tons and tons and tons of reference data which makes the output halfway decent and the GPU power that will make it's speed halfway decent. Other than that, LLMs are.not."thinking".
