Is it fundamental? I don't think so. GPT was trained largely on random internet crap. One of popular datasets is literally called The Pile.
If you just use The Pile as a training dataset, AI will learn very little reasoning, but it will learn to make some plausible shit up, because that's the training objective. Literally. It's trained to guess the Pile.
Is that the only way to train an AI? No. E.g. check "Textbooks Are All You Need" paper: https://arxiv.org/abs/2306.11644 A small model trained on high-quality dataset can beat much bigger models at code generation.
So why are you so eager to use a low-quality AI trained on crap? Can't you wait few years until they develop better products?
Just imagining if we all only used proven products, no trying out cool experimental or incomplete stuff.
these models are built to sound like they know what they are talking about, whether they do or not. this violates our basic social coordination mechanisms in ways that usually only delusional or psychopathic people do, making the models worse than useless
