A model trained on a very large corpus can't, because these behaviors are different or specialized enough they cancel each other most of the cases. You can forcefully fine-tune a model with a singular person's behavior up to a certain point, but I'm not sure that even that can capture the subtlest of behaviors or decision mechanisms which are generally the most important ones (the ones we call gut feeling or instinct).

OTOH, while I won't call human brain perfect, the things we label "shit" generally turn out to be very clever and useful optimizations to workaround its own limitations, so I regard human brain higher than most AI proponents do. Also we shouldn't forget that we don't know much about how that thing works. We only guess and try to model it.

Lastly, searching perfection in numbers and charts or in engineering sense is misunderstanding nature and doing a great disservice to it, but this is a subject for another day.
