问答题 My idea to change the world for the better is to abolish money. That"s technically very easy and possible already. We have plastic cards on which we can store money. We have Internet bank accounts through which we can make transfers and actually we carry around mobile phones all of us that have smart cards on them that we can transfer money, too. So it"s technologically possible. If we did it, we would be able to do without wallets and purses and that would save us quite a lot of bother. But the larger effects would be transforming the kind of society in which we live, and in particular, making us all more secure and bluntly all more honest. There"s no point in robbing banks or mugging people if they don"t have any money, and right more than that, even things that aren"t for money, crime for money, typically uses money. I"m told there are not many drug dealers that accept credit cards or cheques, for example.
