While the our industrial capabilities are indeed incredible there still is an insane complexity gap between finely threaded screws and nanometer pattering ultra-purified materials, treating them with some of the most aggressive chemicals known to mankind as a mere cleaning step. The complexity of the patterns, so intricate that people can't even design them by hand anymore. Or those barely-practical national treasures that are EUV lithography machines. And all this is mass-production. There recently was an article on HN that fabs install microphones and other environmental sensors everywhere and use deep-learning to extract QA information from the sensors.
