Wow, this is incredible. I don't think the fine details of the discussion are very interesting -- all three of them are preaching to the choir where I'm concerned -- but the exchange is fascinating. Thanks for sharing!
This paper cites what I am officially nominating as the greatest paper of all time, Herbert & Simon's 1970 summary of their Odyssean Problem Solving framework: https://iiif.library.cmu.edu/file/Newell_box00018_fld01306_d... So, you know, would recommend that if you find this intriguing! You can't help but smile at the pure unabashed nerdiness "Well, I always end up talking about computers. I’m in love with computers."
Perhaps my only commentary on the text itself is that I was shocked to see him in such an openly philosophical mode... a good reminder that computer science is an upstart offshoot of Philosophy of Mind and Formal Logic.
