What do you expect to be the most important change or development in the world in the next ten years?
In my opinion the biggest change in the next ten years will be more frequent use of payment cards. Paying by card is much safer because it is only a piece of plastic - all money is in your account. In case of loosing it or stealing you can block the card by calling the bank to make it useless. It also makes your life way easier; no more worries about not receiving your change in the store or paying in a different currency. Paying by card brings a way more possibilities than doing it with cash so in the future it may be the only payment method.
