I don't understand how they messed this up so bad. They say they didn't know it could hallucinate and that they thought it was just like any other search engine. But it seems like even if it worked like they thought, they'd still have fucked up? If it's just like a normal person, if that person isn't a lawyer, you wouldn't ask them to do your lawyery work. I'd hope this lawyer doesn't his kids to do his work for him. If it's just like a normal search engine, we all know how much bullshit, spam, and misinformation there is on the internet (mostly written by normal good old fashioned humans!). So that wouldn't have been trustworthy either! There's no way this kind of thing is excusable.
