So much of this is going to hinge on what "smarter" means. My local library has heaps more knowledge than most individual people, but it'd be weird to call it "smarter" than a person.

And automation is generally cheaper and faster than human labor, but that's not a very compelling definition of "smarter" either.

But, as of right now, LLMs can't generate new knowledge or validate their own outputs. We'll need a pretty significant breakthrough for that to change, and breakthroughs are pretty unpredictable.
