Personally, I am against the formation of such a society, where only non-cash payments are common. This creates excellent conditions for the state control on citezens. I think that both digital and fiat money should exist in parallel.
I think cashless society is never going to happen. Even if we are now slowlyvusing some card as a payment system because of new technology but there are also fiat money because fiat money is the most trusted one. Digital payment may happen but it can maybe takes a long time to be use upon the people around. Fiatvmoneybfrom the government is really different from digital money they have many different.
