Pretty much. I forget who is responsible for providing it, but one summary of the Penrose argument is:

That's basically everyone's summary of the Penrose argument about consciousness and quantum effects. I don't think you can ascribe it to any one person.

The summary his argument against hard question AI is even better. Human consciousness is special. Computers don't have that specialness. AI is therfore impossible.
