In the future world, I feel it should be similar to what is portrayed in science fiction movies and novels. Even if people are broke, it's better to live than to die; maintaining a good body and mindset while waiting for the future is important. In fact, everyone can live a life that even the wealthy cannot achieve now. Of course, if you can slowly earn a lot of money now, when the AI world and the mirrored world arrive in the future, you will be among the first collaborators or participants in creating that world. I feel it won't be far off; it should be before 2040 when glasses will replace smartphones. The book also emphasizes the indispensable role of blockchain in the world, so everyone must save funds well. Even if you only have ten thousand dollars, when a huge transformation occurs, if you invest that ten thousand and are just a week ahead of others, you might earn millions, just like when Trump first emerged.
