Maybe you've used it-- but a very large number of the AI skeptic comments I see that actually cite particular experiences, even comments in the pages of HN, amount to things like, "ChatGPT hallucinated when I asked about the local price of product X and if it was in stock anywhere around. How can anyone take LLM and AI seriously?"

Or worse, things like "Real science and real engineering doesn't rely on tools that behave randomly.".
