Darpa's LifeLog "canceled" the same day Facebook was founded (Feb 4, 2004).
A quote from the LifeLog wiki "take in all of a subject's experience, from phone numbers dialed and e-mail messages viewed to every breath taken, step made and place gone"
For those who haven't heard of "LifeLog", I highly suggest you read both the Wiki and Wired article I have linked below. If any of you have additional articles related to this, I would love some more information myself.
The Wired article that mentions that the project was cancelled due to the invasion of privacy it would create.
The is the earliest article I can find that references this.
The date of th article also happens to be the same date Facebook was founded. Could be a coincidence? The core part "conspiracy" is not only the date, but also the objective that LifeLog was attempting to achieve, and the similarities of what Facebook had become.
