At first it was people's phone numbers, then their birthdays. Then I began taking photos of the doors of my hotel rooms so that I wouldn't have to remember my room number. And I think I hit the point of no return when my map on my phone wouldn't work when I was walking around a small town in Mexico, so I took photos of all the street signs based on the logic that I'd be able to retrace my steps if I got lost. I look forward to wearable electronics that rely on facial recognition to tell me everyone's names so that I can stop remembering those too. I'm ready for brain 2.0.
