Not to undermine the technicians, but there is a certain view to it. Let's say an artist comes up with an idea for an intricate lounge chair. It takes them two days to sketch it on paper. Art technician and manufacturing engineer work together to draw "schematics" of the chair in some CAD software to actually manufacture the chair, which takes them full two months of labor. Would their work be more or less significant if it was generic stool?
