Regarding perfection: machines are much more capable of perfection re: manufacturing than humans. Where I think we get confused is that in the past only corporations had the capital to mass-produce, and they have an incentive to "race to the bottom" in terms of production cost. Although it's not the goal, usually quality suffers as a result. So, we associate mass production with poor quality.
I've been spending a lot of time studying historical armour manufacturing and also rocketry. It's clear to me that the goods manufactured by passionate, talented, (and largely under-capitalized) craftspeople are inferior to what could be made by automation. It's just that they're often superior to what is actually made by cost-cutting automation.
Note: I'm all for people "geeking out" about their interests. As we automate more work, people will need more hobbies.
