And those fellas who've dreamed up that 3D printer are pretty impressive. and maybe it'll keep manufacturing on some kind of life support. But I don't think they're craftsmen. They're skillful, sure. Hell, I don't have any idea how that stuff works. But those guys don't use their hands to make that stuff. Odds are if you placed something they created in front of them, said it was broken, and told 'em to fix it, their heads would probably explode. They make the computer do it for them, which is a set of skills I don't possess and it surely deserves some credit. But I fear the day computers do everything for us and no one knows how to do anything themselves. That's what your example of the 3D printer represents to me.
The hunter could not figure out what value the farmer saw in tilling dirt.
The potter didn't think much of the tinsmith taking his market.
The smith thought those fools making machines that people had to pedal were doing the devils work.
I can't mend a clay pot worth a (pardon the expression) tinkers damn, nor can I shoe a horse or sod a roof. My tool box is fairly full of gizmos, not a one of which can I employ to decently fletch an arrow.
Point? Well, my tools and my tinkering fit a time and a place and the things I can do without thinking twice might as well be black magic to my predecessors and will likely seem anachronistic to my childrens children.
I see a direct lineage from banging flint for fire to hitting the print button to make a firearm. It's all the economies of utilizing time and resources and the capacity to invent.
If my great grandpa were presented with a broken harness he would repair that leather until there was more hide holding the harness together than the horse.
If my battery won't hold a charge I'll run a series of tests to pinpoint the culprit, maybe clean it up if my investigation allows or maybe buy a replacement for whatever is faulty and maybe buy a better replacement so it doesn't happen again.
If my successor prints a goomus say gom that doesn't improve his bimbling, he might get a better printer or better media or tweak the program or reverse the polarity of his flux capacitor.
He's fixing the problem. Not like I am inclined to fix, but then my way of fixing is unlike my grand dads.
Somewhere in time somebody said that the Davidsons, the Hendees and the Wright brothers were not craftsmen, that Daimler was making something that would end up shriveling our legs up from lack of use.
C'mon Luciferiad, this old world already has ample flat earthers. Tomorrow is going to be... shiny.
