This guy really hates Penrose: "...Penrose and others have spec- ulated that gravity is crucial for a proper understanding of quantum mechanics even on small scales relevant to brains and laboratory experiments, and that it causes non-unitary wavefunction collapse [35]. Yet the Occam’s razor approach is clearly the commonly held view that neither relativistic, gravitational nor non-unitary effects are central to understanding consciousness or how con- scious observers perceive their immediate surroundings: astronauts appear to still perceive themselves in a semi- classical 3D space even when they are effectively in a zero- gravity environment..." Ugh. That is really lame. People still cite his 1999 article [1] on how the brain can't be quantum, as if that was the end of the discussion. Meh. Anyway, now he seems to be saying the opposite of this, while cleverly avoiding contradicting (or even citing) this earlier work.
