This is what I've been saying. We're not so much learning that LLMs are intelligent, we're learning that a lot of what we think of as intelligence is actually just pattern matching.
There's no solid evidence that the brain uses quantum computations. And that's the only definite thing (besides 'magic') that can solidly place the brain out of reach for now.
There's something else that we are missing there- probably at the convergence of multiple biochemical effects (like ion transport).
I’ll wait until the effective number of parameters in ML models is comparable to that of the brain. Then it will be clear whether the brain has something up its sleeve.
