Darius: Do you remember the old OKCupid? Back when you'd write a whole essay about yourself and answer hundreds of questions.
Harper: Vaguely. That was the one with the match percentages, right? Like, 'you are a 97 percent match with this person who also likes obscure German films.'
Darius: Exactly. And according to this essay I was reading by a writer named Ivan, those scores were eerily good. He said every date he went on was with someone he could at least be great friends with.
Harper: And now it's just Tinder. Another deck of faces to swipe through. It's the classic story. A product gets popular, sells out, and then they ruin it to squeeze every last penny out of you.
Darius: See, that's what I thought too. But he argues it's something more specific. A force he calls the 'Tyranny of the Marginal User.'
Harper: The marginal user? What, like the user who's just okay?
Darius: No, the user on the margin. The billion-and-first user. Think about it: if you're running an app with a billion users, and your main goal is growth, you don't actually care about the billion you already have. They're sticky. You care about the next one. The one who might download the app, open it once, and delete it.
Harper: Okay, so you're designing for the tourist, not the resident. But that still doesn't explain why it has to get worse.
Darius: Because of who that marginal user is. The author gives him a name: Marl. Marl has the attention span of a goldfish. You have about 1.3 seconds to show him something shiny before he gets bored and swipes back to TikTok.
Harper: Marl sounds awful.
Darius: Marl has zero tolerance for complexity. If you add a settings menu, he'll never find it. If you add a 'see less of this' button to give users more control, you know what happens? That button takes up a few pixels that could have been a picture of a puppy. Marl is insufficiently stimulated. He leaves. Your daily active users metric goes down. The feature gets killed.
Harper: Wait. So a feature that makes the product better for engaged users gets cut because it performs worse with the most disengaged user imaginable? That's... deeply upsetting.
Darius: That's the tyranny. Your experience is held hostage by Marl. It's why OKCupid couldn't keep its essays and questions. It's too much friction for Marl. Swiping faces is easy. It's why everything becomes an infinitely scrolling feed of garbage content. It's optimized for Marl.
Harper: I don't know, it just seems... too simple. Like we're blaming this one imaginary guy for everything.
Darius: Well, here's the part that really got me. The author says 'Marl' isn't always a person. It can be a state of mind. We've all been Marl. Scrolling in bed, in line at the airport, just reflexively opening our phones.
Harper: Okay, hold on. If we've all been Marl, then it's not a tyranny. It's just us. We're getting the software we're asking for in our laziest moments. It's not some external force ruining things; it's a mirror.
Darius: But is it? Or is the whole system built to find that laziest version of you and trap you there? The design exploits that state. It doesn't serve you when you're at your best and most intentional; it serves you at your worst. That feels like a kind of tyranny to me.
Harper: I'm not so sure. If you put the junk food in front of me, and I eat it, whose fault is that? I could have chosen the salad.
Darius: But what if the whole grocery store is rebuilt to only have junk food, and the salad is in a locked case in the back that you need a special key for? That's what it feels like. And the author, who worked at Google for six years watching this happen, says he hates this force, but he doesn't know how to fight it.
Harper: So we're just stuck with Marl.
Darius: I think so. I honestly don't see a way out of it either. I'm Darius.
Harper: I'm Harper.
