When it comes to making money, working for yourself, working for someone else in a job, or contributing to society in any way, it fundamentally comes down to several key things.

1. Production of anything can create value for yourself, others, or society.
2. Value is what is being sold or provided to others
3. Creating value is usually in the form of solving problems, filling a need, or creating something that brings joy or interest to others. New ideas or creations can also provide value.

From these fundamentals, one can learn how to become an effective member of society, community, or to others. Money is not the root, the root is the ability to produce value for others. So even if society does not end up using a form of currency, be it from AI evolution, a natural disaster, or a recession or depression, creating value of any kind is the key to moving forward.
