It has been brought to my attention that the discussion threads for Parts 1, 2 and 3 of "To Be or Not to Be (a Local Realist)" and "On the Origins of Quantum Correlations" are getting increasingly unwieldy and slow, due to the huge numbers of comments. Since there have also been recent further contributions to this discussion on the arXiv, from Richard Gill and from Joy Christian, I am opening up this thread for new discussions about these recent papers. Please be polite and reasonable in your responses. No personal comments are necessary.
