In sum, this mountain of data -- more than 350 gigabytes worth, not including the streaming audio and video -- is a replica of Bell's biological memory. It's actually better, he says, because, if you back up your data in enough places, this digitized "e-memory" never forgets. It's like having a multimedia transcript of your life.
By about 2020, he says, our entire life histories will be online and searchable. Location-aware smartphones and inexpensive digital memory storage in the "cloud" of the Internet make the transition possible and inevitable. No one will have to fret about storing the details of their lives in their heads anymore. We'll have computers for that. And this revolution will "change what it means to be human," he writes.
