Because people know they make mistakes, and aren’t always 100% certain and are capable of referring you to other people. Also because the mistakes LLMs make are entirely unlike mistakes humans make. Humans don’t generate fake URLs citing entirely fake references. Humans don’t apologize when corrected and then re-assert the same mistake. Also because we know that people aren’t perfect and we don’t expect them to be infallible, humans can break out of their script and work around the process that’s been encoded in their computers.

But most people do expect computers to be infallible, and the marketing hype for LLMs is that they are going to replace all human intellectual labor. Huge numbers of people actually believe that. And if you could convince an LLM it was wrong (you can’t, not reliably), it has no way around the system it’s baked into.

All of these things are really really dangerous, and just blithely dismissing it as “humans make mistakes, too, lol” is really naive. Humans can decide not to drop a bomb or shoot a gun if they see that their target isn’t what they expect. AIs never will.
