In some point we will be ready to transform. Many benefit can be made with cashless society. Some are no need to carry cash physically, printing of currency cost will be saved, environmental friendly, formalization of economy, possible low inflation and many more. We can discuss this indefinitely but main thing is that some countries are example for this usage, Sweden is my word. In this concept they are ahead of every country in the world.
What that ready should mean? You think if you or someone else is not ready, that transition will wait? Forget about that, in some countries cashless society is already announced, and when that rule spread to other countries people will have to adapt, nobody will ask you are you ready or not, it will happen.
Society is ready for many things, but the governments are playing important role in moving forward. Question is do they have infrastructure for the future? Or they are still using typewriters? Maybe they don`t have even that, still pencil and piece of paper and wrote it down.
