I think that bitcoin being a crux that will lift the civilization in a new age is a bit of a stretch and exaggeration in my opinion because it's not like bitcoin is going to be able to solve the wars or the hunger around the world alone. Can bitcoin power cities with energy? I don't think so, you want to know what the foundation of our civilization is? It's electricity, try ro remove it out of the equation and we will have millions of death in just 2 hours without electricity.
I understand what you are trying to express, but the question you are asking is exactly the problem that exists in our current civilization, whether it is war, hunger or energy. And I think these problems are exactly the problems that Bitcoin can solve in the future, and we need to think about it from two aspects.
The first aspect is Bitcoin itself. Bitcoin itself can exist as a world currency in the future, reducing the common people or weak countries in the world from being exploited at the currency level, and avoiding their wealth from shrinking in constant inflation.
The second aspect I think is more important, and that is the thought represented by Bitcoin, or Satoshi Nakamoto's thought.
I think the real Bitcoin idea is decentralization. We can follow this idea to carry out social changes, and we can conduct experiments on decentralized governance. In this way, we can establish a more fair, free, and equal social order. Only by establishing a set of social order can it be possible to fundamentally solve the war, hunger, or energy problems that our society is facing.
