Will bitcoin become "the motor of the world"?
Heh, no.
But it might become that static motor John came up with before he disappeared.
I still prefer to think of Bitcoin as Galt's Gulch, which we can easily disappear into if we wanted to "exit" the economy.
A rather interesting idea with implications. Consider the case of some country under severe economic duress and facing near term collapse. The ready and fluid availability of an alternative and substitute currency places a limit on the extent to which that government can impoverish it's subjects.
That's a game changer.
