Like with so many other things today, computerized production is able to achieve "good enough" for the vast majority of people, at a greatly reduced cost, which pushes truly high quality into an ever smaller and more expensive niche. That, in turn, decreases the number of artisans who keep the knowledge and experience alive, which can lead to a gradual loss of the expertise. Eventually we get homogeneity of quality and cost for all but a few who can afford bespoke articles.
When everything still involved hand crafting, there were variations in quality and price. But a maker who took pride in their product would put in the extra effort. Partly because their methods became easier to carry out from practice and experience, and partly because they believed their beautiful work deserved to be in the hands of more users, for just a bit more, average people could get top quality.
