You seem to have a capable CEO that is able to bring in the funding. Unless he is blatantly lying I'd say what you are experiencing is pretty standard. Throwing in some buzzwords is not selling snake oil. It used to be "big data", now it's "AI", next it'll be "blockchain".

This is pretty close to fraud. There's a huge difference in return to investors between skilled data scientists doing one-offs, and an engine that does the work on its own.

This is kind of the crux, right? If the investors believe that there is a future roadmap to essentially automate what the team is doing ... That's one thing. If they are investing today because the CEO is saying "Look! It's automated!", then that's pretty much on them.

I don't think there's going to be a fraud lawsuit here.
Theranos was changing the output data that the investors saw, not just saying "we do blood tests better!". That was straight up fraud because the data reviewed in due diligence was false.
