Prompt:
> Alice, who is an immortal robotic observer, orbits a black hole on board a spaceship. Bob exits the spaceship and falls into the black hole. Alice sees Bob on the edge of the event horizon, getting closer and closer to it, but from her frame of reference Bob will remain forever observable (in principle) outside the horizon.
>
> A trillion year has passed, and Alice observes that the black hole is now relatively rapidly shrinking due to the Hawking radiation. How will Alice be observing the "frozen" Bob as the hole shrinks?
>
> The black hole finally evaporated completely. Where is Bob now?
O1-preview spits out the same nonsense that 4o does, telling that as the horizon of the black hole shrinks, it gets closer to Bob's apparent position. I realize that.the prompt is essentily asking to solve the famous unsolved problem in physics (black hole information paradox), but there's no need to be so confused with basic geometry of the situation.
