[contingencies]

I went through each quote carefully while adding some missing ones to my fortune clone/database at https://github.com/globalcitizen/taoup and noticed two things versus modern sources: (1) The weight lent to optimization related concerns seems higher than today. (2) Comprehension of the non-electronic context of programming seems higher than today.

I think these are probably valid cultural reflections, potentially ascribable in part to the (edited, time-lapse) nature of paper-publishing versus electronic.
