Paper money will have not that bad future, there are also a lot of people that is still using paper money in the future and that is not that bad because they dont even know what Bitcoin is.
Especially the older generation people dont know what Bitcoin or digital money is and how to use it.
I have a different opinion on this we can not fight of the times phone keypad is becoming obsolete. many people prefer to use a touchscreen phone. maybe I would analogize like that.
I'm sure fiat would have a different version of paper money. I cannot predict the future of paper money
No doubt about that, everything in this world evolve, like what you've said, cellphones from keypad to touch screen, and same as the computers they evolve too, but even if they evolve, they are still in their original form, like the monitor, from CRT to LCD and LED, it still not far from each other in their functions..same as the paper money, it might evolve, might go smaller or new added security features, but still ti will be a paper money..
