This article is one of the foundational literature in the field of technology and labour. Most of the literature I have reviewed had the name of this author and this article as an important reference text. The article helped me to navigate through the diverse correlations between different sections of labour, different automation, and technological interventions. A holistic view of labour with regard to production patterns and technology lead us to the hidden social, economic and political factors involved in it. In fact, the graveness of the mistakes I always commit was reminded by the author. Totally speaking, the author's argument of heterogeneous labour and technology that must be understood in the context of time and space is sensible along with his empirical evidence. This study gives us a basic analytical tool and cautions us about the inevitability of influence by popular notions.
