That's a really, really high skill job that's been turned into Ikea furniture by computers.
Another example is my kid's invisalign braces. After the first set of prints were done she saw the orthodontist a total of 6 times for about 3 hours total; and she only saw him that much because her teeth needed some grinding and that takes a while. Everything else was done by computer in Israel. The invisalign were the same price as regular braces; but the regular braces would have needed bi weekly adjustments. With the invisalign she just swapped out clear plastic retainers.
Oh, and don't get me started on how quick buildings go up now. I've seen high rises open in less than a year. The kind that used to take 5 times that when I was a wee lad. And most of that year was waiting for the city to complete inspections (underfunded inspection offices don't have enough manpower, so you wait a while).
Point is, it's not just automation, it's massive amounts of skill reduction.
