The structure of a neural network, in terms of how it mathematically produces qualia, is a tool in our environment we don't fully understand. We don't know why neurons in this particular shape produce qualia.
And then we made artificial neurons and tried putting them in similar shapes. Some parts are different, some parts are the same. LLMs definitely share our language skills and produce language the same way our Wernicke's area does. But they definitely don't have the same critical thinking skills. So clearly we copied some functions of the brain, but not all of them.
We don't know if we copied qualia.
