From J.K. Appleseed, writing in McSweeney’s:

How awesome would it be if you could partition your brain in the manner of a computer’s hard drive?

You could devote 7% of your brain to operate in foreign languages, 5% to cooking Italian food, 5% to knowing kung fu, and let’s say 23% to seduction techniques, just for starters. The sky’s the limit! Especially after you devote 5% of your brain to learning how to pilot a helicopter.

A modular brain would be so much easier to manage. You could selectively delete all unnecessary pop lyrics, reality TV show trivia, and the films of Zack Snyder. I would, however, suggest retaining the meta-memory of hating his movies, even though you no longer remember what they were, so as not to repeat your mistake. With the cleared up space, you could now set aside 5% for learning to play blues piano!

We’re only up to 50% at this point. The world of your brain is your oyster!

Right.

Meanwhile, your actual noggin is an undisciplined soup of useless details. You don’t remember where your car keys are, but you can’t get that stupid lick of Katy Perry’s “Roar” out of your head. You know the one. It goes, “Whoa, whoa! Oh, oh, oh, ohhh!”
