In China, you can’t exist without a smartphone, because for all existential things you have to do (paying bills, buying tickets etc.) , you are forced to use the almighty wechat app. Smartphones are a tool to manipulate and to spy on the population. It is a tool utilized by the ruling class, to control the masses. I hate the future and I hate “progress”.
Cash and other physical payment methods (Gold, silver, Goldbacks) are important. Same goes with email instead of phone numbers since email can essentially be free while phone numbers cost money to be registered and email is easily accessible on a computer and does not require a phone.
