To put it another way: a generalisation of OP's question is "is it worth spending a lot of effort learning to do X manually, when a machine can do a lower-quality version of X massively faster and cheaper than I can ever do?" In the article, X = coding. I wanted to check if the arguments given for "yes, and" hold for different values of X and the first that came to my mind was rugs; probably unfortunate that I know nothing of that topic...
I don't think that the answers for one value of X always apply completely to other values of X (i.e. whatever happened to hand-woven rugs might well be very different than what happens with coding) but I found it an interesting thought experiment, because I can fully see a master artisan of any type of X giving a very close version of the article's arguments. Maybe finding when they were eventually right and when they were not for past scenarios can teach me something now. Maybe...
