There seems to be a real under-appreciation by the Hacker News crowd of how profound the use case of cryptocurrencies as simple money is.<p>Perhaps because we have a sample bias towards people who are served adequately by traditional financial infrastructure, and people who are disproportionately preoccupied with blockchain as a potential component of software systems.<p>As an example, most kids in starting school today will probably have years of experience being their own banker, using apps on their phones, before they ever step foot in place which employs bankers. At that point they may not bother, since the cryptocurrency ecosystem will already provide all the same facilities. This is profoundly disruptive.
