Nowadays most people use electronic money instead of banknotes, so the process of eliminating cash has already started. Developing and launching CBDCs will take up to 5 years. It will take above 10 years to become finally cashless.
I am ready to say that in 2050 there will be no cash in circulation as we are now accustomed to it
And it seems to me that 10 years is not enough, because there are very underdeveloped countries, they will take longer to make the transition
It is unlikely that cash will disappear in a hundred years. Even the Chinese government, which is already testing its digitized yuan, has warned the country's population that it is not worth abandoning the use of cash. Each type of money has its own advantages and disadvantages. Cash is sometimes simply irreplaceable both in certain situations and in relation to certain categories of citizens.
In addition, cash is not tracked and any type of non-cash centralized payments is fully tracked by the government.
An example that should people do look on how government do really still minding of paper fiat even though they are already introducing digital ones.
