My multiple experiences with ChatGPT hallucination, even at minimum temperature, leaves me preferring a web search answer. Just last week, jq hallucinated three different jq syntaxes that failed to parse.

That being said, I had been using web search for several years looking for the Get Smart episode I had seen as a kid in the 1980s where the enemy agent explains that he can't give up his suicide ring because "That's how it works, if I take it off, my wife will kill me." Google Bard found the episode on the first try.

So, I tend to fall back to LLMs only when search engines fail me.

Mental inertia is the phrase I use for preferring the one you learned first

Power usage, latency, ethical concerns.
