This is superb, and I'm only on page two. I'm thankful that Rich finds the time to produce his thoughtful content and I hope he has the opportunity to present this at HOPL-IV when it is rescheduled. The distinction between Information Systems and Artificial Systems is the key point to me and reflects my experience, not that I understood it at the time. I use Clojure today because it is a better thinking toolkit for Information Systems (or the inelegant 'Products' as I defined them in my conj talk). I'm an order of magnitude more productive in Clojure than I was in Java. It's not a small step, it's a step-change.
