> It could simply be that everybody knows that blue collar job are eventually going to disappear. You don't want to build your latest factory using technology that will make you obsolete in a few years. This is circular reasoning. Blue collar jobs will only disappear if no-one builds factories using them, because everyone knows these jobs will disappear. > you know such a process cannot include human Sounds like you're just assuming this is true, because "more tech is always better/faster/etc". I'm not so sure this is correct.
