I believe that cash paper money will be in demand even in the distant future and will be actively used by people in everyday payments. Of course, non-cash money is gradually replacing cash, but up to a certain limit and depending on the level of development of the state, the degree of urbanization and the level of income of citizens. But in some cases, cash is simply irreplaceable and if cataclysms periodically occur on our planet, and we see that everything is heading this way, then cash in extreme situations, when there are failures in the operation of technical means, will continue to be used.
In addition, it should be remembered that cash is the least traceable by government agencies and in this they are similar to cryptocurrency. In addition, states and their banking systems set too many different restrictions on the number of maximum amounts and the frequency of transactions, which leads to periodic blocking of transactions with subsequent explanation of sources of income, the need to prove the absence of intent to commit fraudulent actions and many other similar situations that significantly complicate the use of non-cash money.

Well, digital payments still rely on power and reliable Internet access. Without these, you won't be able to pay for goods and/or services. That's where cash comes in. It can be used offline, especially during emergency situations (power outages, natural disasters, etc). I hope physical coins and paper money stay with us for a long time. We don't want central banks and governments controlling our financial life with their digital currencies (CBDCs). At least, I don't.
Anonymity and privacy are one of cash's main benefits. It's no wonder why criminals still use cash on top of everything else. Once cash is "phased out", Monero will save the day. Just sit back and relax. There's nothing to worry about.
