This is one of the areas that ML robotics companies should look into. Prefabs for whatever reason do not seem to work for the American market. Enough is enough, time to start throwing ML robotics models at zoning and building code regulations, instead of those silly game environments that DeepMind use for their RL demos. Replace those overpriced and incompetent tradespeople and builders. They do not have enough real competition and the work quality suffer. Since importing labor from mexico is politically unpopular, use robotics instead. It plays well with both sides of the aisle. Time for the blue collar workforce to experience disruption.
