Oh, you're absolutely right. I didn't realize that GPTs are of course an ANN variant, I always envisioned them as essentially very large and boring vector databases.
I might want to rephrase: not all neutral networks are LLMs.
I personally hate the current "AI" scam with all my heart and I'm so very aware of the extremely limited utility and unsustainable resource demands of the GPT approach. But I have no problem with the more abstract concept of neural networks per se. I expect them to be quite fundamental to any attempt at "real" AI, if we ever get past the current craze.
