Satoshi is the secret
Something I realized this morning, among other things, is that it is not the Bitcoin which is the only genius; It's the Satoshi (1/100,000,000 of a bitcoin) which is also a brilliant bit because it gets people ready to think in terms of very small unary units: Units small enough to want to automate their processing away. It teaches users to think about the hidden tax: inflation. It teaches to any user with eyes to see to think of currency as fluidity, not something solid, i.e. a bar of gold.
