Not yet. Maybe I'll still be alive when we figure that one out. For now, the most advanced brain surgery I'm aware of is to cure drug addicts of their addiction by scanning their brains while showing them images of drugs and paraphernalia to find where it's located, and the using ultrasound to operate on that region.

Humans do something more impressive: we indirectly figure out what the wrong weights are and correct them - just by talking and/or drawing. Theory of mind is our unreplicated super-power.

The closest thing to this would seem to be Mad Cow Disease. Cows eat the brains of other cows, and their brains go bonkers.

LLM is just a computer program, we have binary code for it. The human brain is not. It would be unethical to even attempt that.
