It’s now fashionable, when something has you mildly obsessed, to say that it is “living rent-free in your head.” Well, in my case, that something is an earworm—Bo Burnham’s catchy, creepy, poignantly acidic song “Welcome to the Internet.”

I can’t be alone. The song, part of Burnham’s new hour-plus Netflix special, Inside, has been consumed on YouTube and Spotify more than 54 million times. The Internet’s near-utopian promise of speedily disseminating knowledge has, for Burnham, revealed itself to be a cartoonishly bad deal. We’re not enlightened as a result of this; we’re addicted, distracted, and motivated, much of the time, by the wrong things. We’re suckers in a pitilessly profiteering world. In Burnham’s song, during which he dons the persona of a sort of psychopathic P.T.

To get this out of my system, I thought I’d talk about the song—particularly its portrayal of the Internet as something pervasive and enticing that messes with our cognition—with a scientist. Specifically, I asked Lorenzo Cecutti if he would watch and react to Inside’s centerpiece track. He’d just published a conveniently germane article in Nature Human Behavior, the title of which aroused my curiosity: “Technology may change cognition without necessarily harming it.”
