What is a zettabyte, what is exascale supercomputing, and what could be achieved with that massive amount of computing and storage resources--by entities that the public doesn't even know about? In this post, I’m going to introduce you to some fresh ideas about massive-scale data centers and supercomputing—like the ones used by certain three-letter agencies—and speculate about a possible use case for that enormous scale of storage and computing. Do I know for certain what they use these massive computing resources for? No, I don’t. What I’m going to discuss is (hopefully) just a thought exercise—one that I’ll use to...
