Implementing electronic currency will in itself be interesting. The government will have to be very forgiving of the rural person who trusted the mattress more than the bank. But a huge amount of illegally obtained cash will never be turned in. Clearly we'll need electronic backups and protection. Of course, people will be very concerned that their money is in the form of zeros and ones in some electronic data storage device, but not to worry.
Nothing can go wrong, go wrong .
But some changes will be quite surprising. For example, three generations from now, your average bank teller will dress as a samurai swordsman. By early in this century, British cultural dominance was such that the young Gandhi, for example, would aspire to dress like a London barrister. By now, stylish university students from Nairobi to Kuala Lumpur long to look like an American cowhand, and blue jeans are the universal symbol of American cultural hegemony. Naturally, the world's currency will be some electro-yen marvel, such that all finances, down to getting a pack of gum out of a vending machine, can be handled electronically, with identities insured with flawless systems that rapidly analyze dna sequences, nose smudge patterns, and so on.
