You can program machine intelligent machines to be as nuanced as you want. You want subtle flaws? Just ask the programmer to make it appear randomly throughout the build out and you have your human looking finished product. Old technology suffered from cookie cutter "woodeness". The possibilities as the technology matures are limitless in their abilities. As for the human disconnect I am reminded of my father (an engineer) lamenting that kids today relied on 3D calculators and could not operate a slide rule. I told him a thousand years earlier there were some Roman generals outside the Parthenon lamenting that Roman kids were using slide rules and did not know how to operate an abacus. The more things change the more they stay the same.
