I dont know if im advancing too fast, but in the future we will do all transactions online without the need anymore of the printed money, besides that i do believe we will have internet acess for free, companies will sell just computers and digital equipments.
Real Money will always be paper and digital for use on a network. There is much debate on the subject, just much talk seriously about bitcoin such as international currency very early and premature.
I think the true real money will always be in the form of paper money, and the money will be digital only as an option, although the future of digital money later will be more widely used, but I'm sure paper money will continue to survive
Paper money has to survive until everyone on this world will afford to get their own computer, or smartphone. Another way would be something like a solar powered Trezor wallet to be released and given away to every citizen, but that means a LOT of money. For example, I'm not even sure how India will survive with the e-cash as there are a lot of poor families there.
