” You’ve probably heard politicians or pundits say that “metadata doesn’t matter.” They argue that police and intelligence agencies shouldn’t need probable cause warrants to collect information about our communications. Metadata isn’t all that revealing, they say, it’s just numbers.
But the digital metadata trails you leave behind every day say more about you than you can imagine. Now, thanks to two MIT students, you don’t have to imagine—at least with respect to your email.
Deepak Jagdish and Daniel Smilkov’s Immersion program maps your life, using your email account. After you give the researchers access to your email metadata—not the content, just the time and date stamps, and “To” and “Cc” fields—they’ll return to you a series of maps and graphs that will blow your mind. The program will remind you of former loves, illustrate the changing dynamics of your professional and personal networks over time, mark deaths and transitions in your life, and more. You’ll probably learn something new about yourself, if you study it closely enough. (The students say they delete your data on your command.)”
