Interesting point marshall, but if we study "automatic" I think you'll
agree that in different contexts, the word has different meanings. For
example, none of these machines are truly automatic. They must be
adjusted and set up by hand, man, computer. Also, to set a man cutting
shapes and assembling them by hand is automatic for the designer or head
of an enterprise. You order it and come back the following day and its
done. (Automatic in the sense that the enterprise is the "auto") Indeed,
a man (9axis device) manually stacking sections is perhaps more
automatic than a machine, if that man is sufficiently disciplined and
Its not a pretty picture to consider workers machines, but its not an
unusual point of view.
