I thought so on first glance too, but from what I've heard from someone who worked there, it's working software and it makes a lot of money. That's the opposite of a pipe dream, even if far short of AGI.
My understanding is mostly the latter, but definitely also the former, but it's based off of "I worked there, but our customer list isn't public so I can't tell you who" type statements like you'll see elsewhere.
If I had to guess what it's been actually used for, I'd wager it's money laundering or counter-terrorism type stuff; it's fairly well suited to finding connections between people and entities given a large data-set, and unlike many ML models, it can tell you why it thinks someone is suspicious, which might be needed for justifying further investigation. This is a completely wild-ass guess though so take with a giant grain of salt.
Then again, I felt the same way when I studied it at university almost 20 years ago. It was pretty obviously a pipe dream then, too.
