Humans are the original bullshit generator. AI is only doing what humans have been doing since forever.
A good deal of humans care about the truth. Some of them actively seek to deceive and avoid the truth -- liars, we tend to dislike them. But the ones both sides dislike are the ones who disregard the truth... ie: bullshitters -- the, "that's just your opinion, man," the, "what even is the truth anyway?" people.
While I'm aware of the criticisms of Frankfurt's definition of bullshit [0], I think a useful part of it is the idea that there are folks who don't even care what the truth is. This seems to be the intended purpose of generative AI; ie: hallucinations exist by design and cannot be removed without recognizing that the approach needs to change.
I think that's what gets people like the author to write criticisms like this. We detest bullshit in a number of critical areas such as information retrieval and search.
If you welcomed a giant robot in your house that produces 100x as much shit as a human, you don't have the infrastructure to deal with it.
It was never an issue of yes or no, it's an issue of how much.
Humans get tired.
