> He argues that AI does in no way 'undestand' anything. He goes even further and uses Goedels Theorem to show that 'understanding' itself is non-computeable.

So how do brains understand things? Is he asserting that something is happening in the brain that can't be described/modelled computationally?

Penrose's argument is dualism (humans have souls) with a lot of mathematical handwaving around it involving claims there are quantum computers in your brain. I do not see why it should be respected or why you should think he's different from Deepak Chopra.

Yes. Penrose hypothesizes a non-computational (which would be interesting, because it opens a whole an of worms about how to model it) constituent of the universe. A little while ago he, along with Stuart Hammeroff, proposed the Orch-OR model, which posited that this is the same constituent as what causes the "collapse" of an unmeasured superposition of states into one concrete, measured state. With that said, I have not seen any of his work on this for some time (I last looked at it around 2016), though a cursory look shows some new papers of his on this and related subjects.
