"software is extremely labor intensive work" From what I understand, labor intensive means work that involves some sort of "physical" labor. How would you classify focus as a labor intensive work? An average individual can't maintain focus all the time. But an average individual can do physical work for long hours. The way our body works is different to way our mind works. Are you tired after hard physical labor? You just need some rest and good food. You can do physical labor even if your mind is not in the right place. Many workers in factories are so used to doing the same repetitive stuff (like packaging items in an assembly line or chopping vegetables for a high-paced restaurant) that they do it subconsciously. All they need to do is to get into a "zone". But same can't be said about focus intensive work. You can do physical work without thinking. But can you code without thinking? There is nothing repetitive about coding. And if anything is repetitive we end up automating it.
