But How Do I Back It Up?

The Explainer piece today tells us that the human brain can store a lot of video, audio, and documents.
Most computational neuroscientists tend to estimate human storage capacity somewhere between 10 terabytes and 100 terabytes, though the full spectrum of guesses ranges from 1 terabyte to 2.5 petabytes. (One terabyte is equal to about 1,000 gigabytes or about 1 million megabytes; a petabyte is about 1,000 terabytes.)
So while our retrieval system can leave a little to be desired, our storage capacity still bests most of the hardware you can buy today. It won't be long before that isn't the case no doubt, but before you worry too much about the rise of our computer overlords, remember that the juice just isn't there to run a human brain outside of a human.
