This argument doesn't go the way you want it to go. Billions of people exist, but maybe a few tens of thousands produce novel knowledge. That's a much worse rate than LLMs.

I’m not sure how we equate the number of humans to AI to determine a success rate.

We also can’t ignore than it was humans who thought up this problem to give to the AI. Thinking has two parts, asking and answering questions. The AI needed the human to formulate and ask the question to start. AI isn’t just dropping random discoveries on us that we haven’t even thought of, at least not that I’ve seen.
