As somebody who switched careers from construction to software development, I disagree with your criticism. Systems in a house are largely decoupled and easily extensible and modular. It's a routing affair to add a room or second floor. You can replace all the plumbing in a house without touching the electrical. You can easily upgrade an electrical service and add more circuits and outlets to an old house. The nature of stud framing makes it relatively trivial to run ethernet cable through a 70 year old home, or replace ancient single pane windows with the latest triple pane offering. You can swap out your dumb lightswitch for the latest wifi connected smart home nonsense, all without disturbing anything else in the house. I also disagree that "we're doing the best we can." We're building monstrously complex systems because it pads our resumes, not because it actually solves real problems.
