I think an extended conclusion to draw, which is worth articulating rather than leaving off at a vague notion of humility, is to (try your best to) account for all of our intellectual limitations in the design of the systems that we build. None of us remembers particularly well. No one can run all of the code in their head. The future person who has yet to join your team doesn’t even get the chance to “remember” the reasoning for the decisions that we make today.
