People around the globe and mostly in developing and under-developed countries, paper money and cards will not see their end very soon, at least not in the upcoming 15 years. The mindset is still dependent upon the old values and beliefs. But the thing is with recent changes and acceptance of a paperless transaction UPI which was in the news, things are going to turn around for sure.
Also, India launched its CBDC, Digital rupee, or e-rupee recently, which shows that we are on the path of this but I still believe it is too soon for complete dependency on CBDCs or digital payments.
