I would have considered this article as overly grandiose a year ago. Part of me wonders if there is some possibility that this is becoming a more prevalent thinking. Even if bitcoin crashes to $0.01 USD, it still has some usefulness as a way to transfer value (Western Union's market cap: $2.77 billion).
