Well, A world without Fiat🤔.
Millions of Uneducated and technologically uninclined folks will be digital slaves, they will be the poorest as it will not be easy for them to venture into any kind of trade.
Most importantly, lmagine what will happen when the internet shuts down? Trade by barter! For the everyday person, some cell phone services and text messaging would be unavailable, all mobile apps and social networking sites would be down, cloud storage would be inaccessible, any pending electronic payments would fail, and more...
The world will have to Reboot and we will make our way back to fiat.
