A few points:

• Humans are more than just a brain. There’s the entire experience of ego, individualism, and body

• Another massive distinction is autonomy and liberty, which no AI models currently possess.

• We don’t know all there is to know about the human brain. We can’t say it is functionally equivalent to a neural network.

• If complexity is irrelevant, then the simplest neural network trained on a single work of writing is equivalent to the most advanced models for the purposes of this discussion. Such a network would, again, output a copy of the work it was trained on

When we’ve developed a true self-aware AI that can move and think freely, the idea that there is little difference will have more weight to it.
