The future for whistleblowers is grim. At a time not so far distant, when just about everything is digital, when much of the world's Internet traffic flows directly through the United States or allied countries, or through the infrastructure of American companies abroad, when search engines can find just about anything online in fractions of a second, when the Patriot Act and secret rulings by the Foreign Intelligence Surveillance Court make Google and similar tech giants tools of the national security state (assuming organizations like the NSA don't simply take over the search business directly), and when the sophisticated technology can either block, alter, or delete digital material at the push of a button, the memory hole is no longer fiction.

Leaked revelations will be as pointless as dusty old books in some attic if no one knows about them. Go ahead and publish whatever you want. The First Amendment allows you to do that. But what's the point if no one will be able to read it? You might more profitably stand on a street corner and shout at passers by. In at least one easy-enough-to-imagine future, a set of Snowden-like revelations will be blocked or deleted as fast as anyone can (re)post them.

The ever-developing technology of search, turned 180 degrees, will be able to disappear things in a major way. The Internet is a vast place, but not infinite.  It is increasingly being centralized in the hands of a few companies under the control of a few governments, with the U.S. sitting on the major transit routes across the Internet’s backbone.

About now you should feel a chill. We’re watching, in real time, as 1984 turns from a futuristic fantasy long past into an instructional manual. There will be no need to kill a future Edward Snowden. He will already be dead.
