I selected tenet number 5, "The Critical Engineer recognizes that each work of engineering engineers its user, proportional to that user's dependency upon it."

This means that engineers and their engineering projects form a sort of symbiotic relationship, both relying on each other and making each other better. The first thing I thought of when I read this tenet was Newton's Third Law of Motion, which states that every action has an equal and opposite reaction, in a way relating to engineers and their work, where both have an equivalent effect on one another. One example of this is machine learning. In machine learning, humans program a machine to perform some tasks, and learn from each of those tasks so that is builds a basic form of AI and is able to accomplish much more difficult tasks independently. Eventually, the machine will be able to teach the human (the creator) how to do those tasks, which illustrates this dependent relationship.
