Most likely, the answer is Yes. Some countries are already moving towards a cashless society, e.g. Sweden. The downfall is that a fiat currency becomes an even more abtract form of payment, as a fiat electronic currency. Not exactly something that instills confidence in a currency. The upside is that street crime over cash will be elminated and tracking illegal uses of money will be easier. Of course, criminals will switch to other currencies, like Tide :-), and big brother will be watching all transaction, legal or not. Brave New World!
