I think right now, cashless society is still hard because not all people knows cryptocurrency and even on economics class, they don`t discuss cryptocurrency so people can`t adopt to a cashless society yet. Cryptocurrency must be exposed more so that people will not be shocked and can easily adopt to a cashless society and to cryptocurrency era. So for me cashless society is still impossible as of now.
You do have a point there, mate. Nowadays, it is nearly impossible to implement a cashless society since there are many people in the world who haven't heard about Bitcoin or other cryptocurrencies. However, I believe that the time will come when governments start issuing their own digital currencies and take the effort to educate people about the subject. Once people become used to cashless payments, then we'll be able to see future generations where there would be no need for physical cash at all.
Technology is quickly evolving, and one way or another, a cashless society would become a reality as it provides greater benefits than those provided by physical fiat currencies. By eliminating cold hard cash, there will be a friendlier environment to the people of the world. Also, there will be greater transparency and the ability to change the monetary supply easily at will. That is the future, and we may become early adopters of the revolutionary technology that will be a part of it. Just my opinion
