How do humans "invent knowledge"? Is your argument that the answer to these questions already existed in the training set? Why didn't any human recognize that before?
humans discover a lot of things by trial and error (aka what I meant by "invent knowledge")
basically everything Benjamin Franklin did was trial and error because no-one understood what electricity was in the slightest
almost everything Edison did was trial and error too, he had his lab try thousands of materials for his long lasting lightbulb filament
even the most advanced "AI" today is just machine-learning going through everything already known trying to piece together previously discovered facts, admittedly at levels and detail impossible by human hands
but that means there are limits and it's not really "AI"
Have you seen how it debugs? It's trial and error. As the most reasonable hypothesis fail, new data is found, and it keeps iterating. It's not a human intelligence, but if it has an issue, it's not some mysterious creativity anima in the heart of man.
I have seen it produce tentative genetics for experiments, just like a scientist does. Then the data comes in and it can evaluate the data from the experiment just as well. One just had to give it a lab budget.
