The author is questioning the concept of division of labor and the associated efficiencies of that type of organization. Without division of labor, each worker must become an independent craftsperson. In other words, they must be able to do the whole task themselves, start to finish, with all of the necessary equipment at their disposal. Some jobs are amenable to this while still remaining efficient. Most jobs, however, including many technical jobs, are not. That is why people work together and in the same location.
If the issue of “Zoom fatigue”, mental health and remote work space can be addressed such that efficiency of labor is maintained or even improved, then remote work makes sense. It would really help save lives from traffic accidents and reduce carbon emissions.
