Reduction in human labor for building these types of structures. The world is getting old fast, but infrastructure is still required, both new and maintenance of what exists today. Also, job assistance that reduces the toll on humans in this industry. This prevents treating the human as a consumable when the automation can be human driven, increasing quality of life and potential career longevity (if desired).

Not replacing humans, to be clear, but helping them build better with less effort. Thank you for indulging me. I hope to eventually leave tech to build things that are needed that are built to last (I too am getting old fast).
