A common scientific view is that the actions of a human brain could, in principle, be simulated by appropriate computation, and even that it may not be too far into the future before computers become so powerful that they will be able to exceed the mental capabilities of any human being. However, by using examples from chess and mathematics, I argue, that the quality of conscious understanding is something essentially distinct from computation. Nevertheless, I maintain that the action of a conscious brain is the product of physical laws, whence consciousness itself must result from physical processes of some kind. Yet physical actions, over a huge range, can be simulated very precisely by computational techniques, as is exemplified by the LIGO gravitational wave detectors confirming precise calculations, within Einstein’s general relativity theory, of signals from black-hole encounters in distant galaxies.

Despite this, I argue that there is a profound gap in our understanding of how Einstein’s theory affects quantum systems, and that there is reason to believe that the events termed “collapse of the wave-function” take place objectively (gravitational OR), in a way that defies computation, yet should be observable in certain experiments. It is argued that each such event is accompanied by a moment of “proto-consciousness”, and that actual consciousness is the result of vast numbers of such events, orchestrated in an appropriate way so as to provide an actual conscious experience (Orch-OR).

I would like to see the slides published, so I can peruse them at leisure.

I would agree that both understanding and intelligence require awareness. But why does intelligence require understanding? I could easily argue that it's the other way around; understanding requires intelligence.

I dont' know i'm not really sold on the idea that consciousness may emerge from some quantum phenomena that gives nature " a chance to pick". that being said i'll read the book and i'll kepp updated with the upcoming developments.

Dear Prof. Penrose, what do you think of the recursive tensor identity 1=[1 0; 0 1]
I've stumbled on it one day and I think it runs deep.

It's 50 move rule not 30 and fritz is outdated

Penrose doesn't understand the universality of computation.
