Hint: it actually doesn't work at real depth, and why not is fairly well explained in TFA: they hype always overestimates the depth of the field. So these advances do help to make easy thing easy (in the case of LLMs because they have been trained on a billion examples of the easy stuff), but don't really end up helping with the hard things (because they really only make new things that weren't encompassed in their training by getting lucky, and because tedious things are different than hard things).
There's national headlines every few months for lawyers getting in trouble for submitting LLM hallucinated citations in court, so lawyers are starting to do it to themselves as well.
It's early days yet, because unlike most CRUD apps, the consequences of hallucinations and outright bad calls in medicine and law are life ending. Unless the bubble pops soon, it's coming though.
