Oh, another thing, too. There are several jobs that the matter-creator can't obsolete for one reason or another. Anything where the product isn't something you'd expect to want, for instance. As just an arbitrary example, I've got a bit of amethyst here that I really, really like the look of. It cost me 35 cents. As far as grades of stones go, it's terrible. I doubt if anyone would ever have programmed a method for producing this particular piece, nor would I have thought to combine this particular shape with this particular color distribution or anything like that. Were it not for a shitty job (mining), it wouldn't exist. I do hope the people involved were paid well, but I'm still glad the work was done.
