I believe that in the modern world, specialization is more common, where ancient skills might have been more generalized.

So comparing to the modern world, I know of one relative in the industry of building homes, but even that person has never "built" their own home, and none of my relatives have bought a newly built home. In other words, in our family the skill of building home is very barely there. We'd likely have to hire out. If, instead, when my parents bought the house I grew up in from my great grandparents, they'd torn it down and built a new one, then the skill would have only skipped one generation, but continue to be exercised within our family.
