In a discussion here on HN about why a regulation passed 15 years ago was not as general as it could have been, I speculated [1] that it could be that the technology at the time was not up to handling the general case and so they regulated what was feasible at the time.
A couple hours later I checked the discussion again and a couple people had posted that the technology was up to the general case back then and cheap.
I asked an LLM to see if it could dig up anything on this. It told me it was due to technological limits.
I then checked the sources it cites to get some details. Only one source it cited actually said anything about technology limits. That source was my HN comment.
I mentioned this at work, and a coworker mentioned that he had made a Github comment explaining how he thought something worked on Windows. Later he did a Google search about how that thing worked and the LLM thingy that Google puts at the top of search results said that the thing worked the way he thought it did but checking the cites he found that was based on his Github comment.
I'm half tempted to stop asking LLMs questions of the form "How does X work?" and instead tell them "Give me a list of all the links you would cite if someone asked you how X works?".
