I disagree that “giving answers is an irreversible operation”. My setup explicitly doesn’t “forget” the calculation (the calculation being simulating someone proving the Riemann hypothesis, and us extracting that proof from the simulation), and my setup is explicitly reversible (because we have the full density matrix of the system at all times, and can in principle perform unitary time evolution backwards from the final state if we wanted to).
Nothing is ever being forgotten. I’m not sure where that came from, because I’ve never claimed that anything is being forgotten at any step. I’m not sure why you’re insisting that things be forgotten to satisfy reversibility, either.
