Everything that is expressed and recorded externally, such as cell phones, computers, memos, books, and drawings, is an extension of the brain. Our brains aren’t just inside our bodies. This concept is important because extending the ego greatly influences how we see the world. We pay close attention to topics that involve us personally. Self-relevance is a key factor that drives our lives. Personal relationships and possessions get a lot of focus, while other areas seem less important. This is due to a feature of the human brain called ‘selective cognition.’ As civilization advanced, humans delegated parts of the brain’s functions to machines. It was inevitable to make good use of these tools. We should take an interest in the Homo Faber. - Joseph’s “just my thoughts”
Before the high level of civilization, human life was tribal. However human beings were needed for the large-scale labor force for industrialization, so people were gathering in the cities for a living. That was the detribalization. These days when we are developed by social media, people are used to selectively make a relationship with those who have similar philosophies and preferences. Rather, the new media makes the retribalization in different meanings. Therefore, now human relationships are becoming more important the interests and preferences. When choosing to make a relationship, people gather according to their preferences. Communication is narrower and more easily ostracized. - Joseph’s “just my thoughts”
