I don't see how it is possible to not end up just memorizing the internet, which is full of enough questions and discussions to simulate convincing Q&As. Consider if a team had invented an algorithm or heuristic to avoid data contamination (https://aisnakeoil.substack.com/p/gpt-4-and-professional-benchmarks). Then what you have is something that can separate content into logically similar, but orthogonal realizations. That would be an incredibe tool and worth a prize in its own right.
