In the same way that component parts can be assembled, why is it that the machine does not understand how the end product can differ, where as the human senses can? It is not that the machine on average will always get it right, but that the smallest of changes in the process, somewhere around the margin, can make the difference and can result in a masterpiece rather than something that is 'good'. We can point at cooking, tuning car engines, timing a watch, tuning the gongs in a repeater... take component parts (as listed), assemble, and there you are... but no, it is not 'there you are'. Somewhere in the mix, genius or mediocraty might lurk, and how the component parts are then put together can alter almost beyond recognition. I dont have an answer, just that the force majeure of the research in larger companies cannot always in such circumstances as watchmaking over rule the smaller element of genius!
