Call me back when Penrose convinces a well-regarded quantum physics expert. At that point we can call up Scott Aaronson and ask him his opinion, as Aaronson is an expert on the intersection of quantum physics and computing.
Scott is a friend of mine. I've talked with him face to face about this very subject. He disagrees with Penrose, but his objections are far more nuanced and respectful than anything I have seen here. He would be horrified to see Penrose belittled and his arguments not given a fair reading. Penrose is an intellectual hero to Scott and someone to be admired.
That's good to know. I read his post on his 'debate' with Roger and really enjoyed it. Also of interest may be the discussion between him and Hameroff in the comments section.
Meta-comment:
It a sad sort of situation when intellectual communities, whether they be HN or another, tend to idolize a set of individuals and demonize others.
Thanks @manyosos for your comments in this thread, you really helped elevate the discourse.
