Human brains are similarly finely tuned and have similar knobs, it seems to me. People with no short term memory have the same conversations over and over again. Drunk people tend to be very predictable. There are circuits that give us an overwhelming sense of impending doom, or euphoria, or the conviction that our loved ones have been replaced by imposters. LLMs with very perturbed samplers bear, sometimes, a striking resemblance to people on certain mind-altering substances.
And that's really a core of the problem, we don't well understand how the human mind works and we can't really define or identify "intelligence."
I mentioned I don't like the stochastic parrot argument, and that I find this article's argument lacking. Both are for the same reason, the arguments are making claims that we simply can't make while missing the fundamental understanding of what intelligence really is and how human (and other animals) brains work.
