I keep saying bitcoin has truly come a long way, but for mass adpotion to be possible, a lot of things have to be simplified. I don´t see grandpa calculating how many satoshis his icecream costs. Bitcoin is like linux: an exquisit hugely useful system for people who know what they´re doing, and it will need to become more like android: a prettier, dumbed down system which is not only super easy to use but also(usually) prevents most dumb users from erasing their own files. See the analogy?
