Roger Penrose, a long time opponent of AI, has proposed that consciousness "arises from wave-like quantum-mechanical effects involving protein filaments in nerve cells"; something he believes can't be duplicated in software. There has been no evidence to support his view in the past but recently physicists have demonstrated quantum effects in biological materials. Tetraphenylporphyrin molecules, a component of haemoglobin, exhibit the property of being both a particle with a well-defined location and a wave that can be in two places at once. While this is far from proof of Penrose's theory it may at least make it plausible.
