Interesting blog post. I think the majority of what you see is that due to how rapidly technology and other fields have bloomed via human involment, and due to how we have become an interconnected society due to the industrial revolution. I think that the major way humans cope/tackle this is via specialisation. While not for everyone, most people seem to find a job in a field, and the work in that field helps us support a more complicated society than we can fathom. Most people can't memorize all the stuff from multiple domains, or they would burn out. Most people don't understand how truly complex a semiconductor is, or how electricity and power is generated, or how to design a car. These are just basic examples but I'd argue a really good example of how humans have chosen a specific domain or thing and over time developed better understandings of the field and topic. The average person could do any job I'd argue. We are not as physical as we used to be, we have "engineered" ourselves replacements. The tractor, the car; both replaced horses but at the cost of needing someone who understood the principal of the new technology. Be it robot workers replacing amazon warehouse employees, or the tractor that improved the farmers ability to harvest or plant crops; both required smart people to not only develop them but to maintain them. I'd argue while we really are less physically active, due to technology and general advancements we have made over the years; this comes at the cost of mental strain. We mentally must process and think more than ever before, pushing our brains to keep up so we can stay relevant.
