Great points. The only reason that Civil Engineering isn't like software engineering is because of cost and legal regulations. It costs only labor to change software. If there were robotic workers and plentiful energy and materials you'd better believe that bridges would be getting refactored all of the time. Also bridges are never done. They are continually inspected and refurbished. Every bridge you build has an on-going cost. Just like software.
