Quants are open about that they just want to make a shitton of money.
The guys I know who work at OpenAI just want an expensive car and a hot wife to fuck.
Mathematicians(and many academics) however have long been hiding behind the guise of furthering human knowledge, understanding things, etc. Then a model does theorem proofs and suddenly there is chaos and the real incentives and motivations are put on display for the world to see.
See professor Williams' thoughts on a recent conjecture that openai proved: https://people.csail.mit.edu/virgi/thoughts.txt
And Williams thoughts are kind of idealistic. "Now the credit is shared across the entire field". This "credit" does not give your department grants or further your own career.
Rather it incentivizes you to be the first one to prompt, and to steal ideas from your peers because you can prompt better and have your name on more discoveries.
