At least 12 exabytes of mostly encrypted data, waiting for the day that the NSA can decrypt it and unleash all of these tools on it.
Whenever that day happens (or happened) it will represent a massive shift in global power. It is on par with the Manhattan project in terms of scope and consequences.
Soon if not already they can just ask questions about people now.
"Has this person ever done anything illegal?"
Then the tools comb through a lifetime of communications intercepts looking for that answer.
It's like the ultimate dirt finder, but without the outsized manual human effort required to ensure that it's largely only abused against people of prominence.
It's gonna be wild to see what secret needles come out of that haystack.
