The introduction of the assembly line has in many ways altered the lives of people (workers and consumers) in the industrialized world. I doubt there is a large group of people who think the assembly line is an altogether negative creation. In fact, a large majority of people would say the assembly line is one of the most beneficial introductions to ever enter the workplace.
Still, I think we should recognize the limitations of the assembly line as well the innovation's benefits. This mode of production can never replace the competence of a trained artisan. The two means of production are best when they compliment one another rather than compete with one another.
