The speaker believes that life is the physics of existence, the combination of abstract concepts like computation and information with the physical world of matter. They compare it to ancient times when people didn't understand that stars and heavens were governed by the same principles as Earth.
The use of computation and simulations can help make complex physics concepts more accessible to those who aren't specialists in the field, allowing for a greater understanding of abstract ideas. This could lead to a more efficient and compressed approach to teaching physics concepts in the future.
The comprehension of difficult concepts is often underestimated as most people can understand complex ideas like multiverses and quantum physics. Once a concept is understood, it may seem simpler than initially perceived.
While a theory of everything attempts to explain the underlying fundamental principles of the universe, it falls short in understanding macroscopic objects and emergent behaviors that cannot simply be derived from the theory itself. As one moves to different levels of explanation, new ideas and ways of thinking are needed to understand the complexities of the world around us.
The incredible evolution of technology has brought us from flying tins to cell phones with FaceTime, and it's mind-boggling to think about the progress that has been made. We don't need to understand how things work to utilize them, and the growth is only going to continue.
The process of using math to understand our world is often seen in physics as it allows us to reach beyond our current levels of understanding, but the actual world is a gray area when it comes to interpretation and description.
