In the years following World War II, we've seen an incredible amount of change and progress. However, these changes haven't been as groundbreaking as those that occurred before World War I. Despite this, it's important to note that more people today have access to a higher standard of living and better health than ever before, even though this group only represents a small portion of the global population.

Our understanding of the world around us, from the universe to the atomic and genetic level, has grown exponentially. This knowledge has led to the creation of a wide range of machines, devices, and procedures that form the backbone of modern civilization. But, there's so much information out there that it's impossible for one person to know it all.

In the past, polymaths, or people who are experts in many different areas, could grasp the full breadth of knowledge. Today, even experts find it hard to understand research outside their specific field. This makes it difficult for the public to make informed decisions, as the science becomes more and more specialized and complex. This was evident during the COVID-19 pandemic, where experts often disagreed on the best course of action. Those without specialized knowledge found it hard to understand these disagreements, which often led to confusion and misinformation.

This lack of understanding isn't just due to the specialization of knowledge. It's also because of urbanization, mechanization, and a societal shift towards prioritizing information over physical realities. Most modern jobs in cities have nothing to do with food production or manufacturing. As a result, many people don't understand how their food and possessions are made. Instead, they're focused on information and electronic flows, which are seen as making physical necessities obsolete. But, this is a fantasy. We can't live on Mars or without physical resources. As we move forward, it will become increasingly difficult to provide for everyone's basic needs, especially as the environment continues to degrade.

To address this, we need to better understand the realities of our world. This involves looking at seven key topics that are essential for our survival. The first topic is our reliance on fossil fuels, especially electricity, and the challenges of moving away from them. The second topic is the role of fossil fuels in agriculture, and why it's difficult to separate the two. The third topic is the belief in dematerialization, or the idea that we can live without physical resources, and why this is unrealistic.

The fourth topic is globalization, and how it's not a new or inevitable phenomenon. The fifth topic is risk, and how we often underestimate or exaggerate dangers. The sixth topic is environmental changes, and how they impact our basic needs like oxygen, water, and food. The final topic is the extreme views on our future, from those who predict disaster to those who are overly optimistic, and why a balanced view is necessary.

This understanding is based on scientific findings and years of interdisciplinary study. It aims to provide a balanced perspective, using numerical facts to support its arguments. The goal is to help people understand how the world works and what our future might look like. This practical, straightforward approach provides a solid foundation for understanding the realities and possibilities of our modern world.
