Well, we didn’t all have the benefit working enough with Ken to be able to predict what Ken would say, …
I would like to point out that I benefited by being very familiar with Ken’s papers, for example I typed in all of A Source Book in APL, which included The Design of APL, The Evolution of APL, and Notation as a Tool of Thought; and Operators and Functions, Rationalized APL, A Dictionary of APL, and so on; and the all-important first chapter of A Programming Language; and Ken’s Ph.D. thesis. (All of these are online in http://www.jsoftware.com/papers/.) Anyone could have done this, but I don’t know that anyone else has.
And yes, I had the good fortune of working with Ken for 15 years on a daily basis in close quarters. Being blessed with a good memory, I apparently remember everything that Ken ever told me. That can not possibly be true, but it sure seems that way.
Even with all of these, obviously I don’t actually know what Ken would say or do.
