It's interesting that at the end of the article the author mentions that the end game is often the creation of a newer better vault. I often wonder what it would be like if everything that was in the biggest best vaults was unleashed to change the wasteland into something better. As it stands so much money and technology gets sequestered away to be used in emergencies or to maintain the advantage. The world could really use some of that vault tech everyone stores away.
Edit: Almost forgot to mention that hopefully the trend of creating new vaults goes away and is replaced with that openness that would let our wasteland prosper.
My different interpretation of that metaphor is that the wasteland is by definition an infinite sink. No amount of resources can make all of it anything other than wasteland. On the other hand, finite resources can make part of the wasteland into a vault, which may be larger or smaller, more or less attractive to different people, more or less interoperable with other vaults etc. But a vault nonetheless.
