Not meaning to get off topic, but if we are still using BTC in 2140 we have failed as a species. BTC is a step in the right direction. I don't see how it can be an answer. (In the short term yes, but not long term.

I was talking about a time, on the horizon, when man doesn't quite feel the need to have power over others with money.
And when that happens, we won't really need money. Money, is a bit of a relic or primitive thing.
Which is ironic, when you think of it...
Its about sharing
