From the past to the present, productivity is the source of wealth for humans. The reason is that human productivity has never caught up with demand. Therefore, the world's top few wealthy countries either have large populations, advanced technology, or energy. But with the emergence of AI and robots, future productivity will be far greater than basic human needs. This is a fundamental change in human society, and finance, economy, and wealth distribution will be completely different. The era of making a lot of money by hard work alone has passed, and choice is the focus of the next generation.
