My prediction is that in 10 years at most, nobody will use paper money, and this will probably start on the side of the states, where they will completely abolish paper money, digitize everything and act more easily.
I bet you that your predictions would turn out wrong. Paper money has been in existence and use for over a century(thats a 100 years). We have gotten familiar and used to the paper money that any other means of payment would be scrutinized thoroughly and initially would be distrusted by most people.
Paper money will almost definitely still be in existence and use in 10 years. Besides, what other means of payment is as widespread, known and accepted as the fiat system? None that I know of.
In 10 years from today, we would still be using the fiat system. There may be other new and innovative means of making and receiving payments, that doesnt mean the fiat system would be completely abolished.
What Hauff Murray is saying is not far from the truth but 10 years are too close to forget paper money. I will say yes and no. Yes because there will a generation that is coming in the future that paper money will be automatically remove, in that generation, everything will be computerized and digitally oriented. No in the sense that, paper money makes things easier for people to buy and sell so for paper money to fade away will take another century. And I don't think Americans leaders will allow that to happen. Because dollar is worldly accepted currency and Americans are making profit from it.
