Less knowledgeable overall, I would agree. LLMs are, if anything, the ultimate knowledge bases. But within our own areas of expertise, our worldview is typically more coherent and we have often learnt to reason optimally within that world view. To be fair, it is hard for me to generalize. So at least that's what I see in areas which I know. As pointed out by others, however, making discoveries that bridge disciplines is where LLMs might have an edge.
