Initially, humans could not draw as they perceived. It was only after the discovery of perspective that they could accurately draw what they saw. Perspective was first applied to performance stages in Greece during the 5th century BC, and it was not until the 15th century that the Italian architect Brunelleschi succeeded in expressing a three-dimensional perspective on a two-dimensional plane. In the long history of humanity, the period of applying perspective is quite brief. Perspective painting represents a virtual depiction of reality. In other words, the first instance of visualizing something virtual is perspective. People speak as if the metaverse is a significant industry today, but the virtual realization through perspective began long before the digital era. Currently, it’s only visually represented digitally. Understanding the essence of this can help you mitigate risk, even as times and circumstances evolve. - Joseph’s “just my thoughts”
Even though a country's total population is decreasing, the economic situation could be improved by increasing the total economic activity of the remaining population after the decrease. Of course, there is a statistical population threshold below which this effect occurs. Nevertheless, this effect would not work in the case of a force majeure, such as a natural disaster or the outbreak of war, however, this assumption would be valid because a rapid population decline is a highly exceptional event that would not normally occur. Therefore, an increase in the economic activity of this population should be required during an economic recession. Applying this perspective, for building a solid relationship with your followers on Instagram, the number of followers is less important than the activity between them and you. This is called the "Engagement Rate (ER)". - Joseph’s “just my thoughts”
