A few months ago, I watched a six-year-old in a pediatrician’s waiting room go absolutely still in front of a tablet. Her mother was filling out paperwork. The child was supposed to be doing a “learning” app — something about phonics, with a cartoon fox. Every few seconds the screen flashed gold, made a small chiming sound, and showered her in animated stars. She wasn’t reading. She was waiting for the next burst of stars. When her mother gently tried to take the tablet, the kid melted down the way I’ve seen adults melt down at blackjack tables when the cards turn cold. It was a small moment. But it lingered.
The strange thing about modern EdTech is how cheerfully it borrows from places we would never knowingly send our children. The flashing rewards, the streaks, the unpredictable little bursts of celebration after a correct answer — those aren’t pedagogical decisions. They are casino decisions, dressed up in primary colors. Natasha Schüll, who wrote Addiction by Design about the slot machine industry, has spent years describing how gambling firms engineer something she calls the “ludic loop” — a tight cycle of uncertainty, anticipation, and reward that keeps a person pulling the lever long after the fun has drained out. Look closely at most children’s learning apps and you’ll find the same loop, just animated by a friendly owl.
There’s a sense, talking to teachers and pediatricians, that nobody quite signed up for this. Schools adopted tablets during the pandemic the way restaurants adopted QR menus — quickly, gratefully, without much thought about what was on the other side of the screen. The apps themselves often arrive bearing impressive credentials: “research-backed,” “aligned with state standards,” sometimes a quiet mention of being developed with input from Stanford. What rarely gets mentioned is that Stanford is also the birthplace of persuasive design, the discipline B.J. Fogg founded in 1998 under a tagline that should probably have set off alarms — Machines Designed to Change Humans.
Fogg’s students went on to shape Instagram, the like button, the pull-to-refresh gesture. Tristan Harris, one of them, later turned whistleblower and described the news feed as functionally a slot machine. Other students went into EdTech. Nobody talks about that part much. But the techniques traveled. Variable reinforcement schedules — the psychological term for rewards delivered on an unpredictable timetable, the very mechanism that makes slot machines so sticky — now sit at the heart of apps designed for children who can barely tie their shoes.

It’s possible that some of this is harmless. Kids have always loved gold stars. Teachers handed them out for decades. But a paper sticker doesn’t ping you at bedtime. It doesn’t track your behavior and tune itself to your weak spots. It doesn’t reward you for opening it again at 6 a.m. on a Saturday so you don’t break a 47-day streak. The streak, in particular, is a quietly cruel invention — it weaponizes a child’s discomfort with loss, the same way casinos weaponize the near-miss.
What’s harder to measure is what’s getting displaced. A child practicing math on an app that fires confetti every twelve seconds may be learning math. She is also, almost certainly, learning that quiet, slow, undramatic work feels boring by comparison. Pediatricians I’ve spoken with describe a particular kind of frustration in children pulled away from screens — not sadness, not boredom, but something rawer, closer to withdrawal. Their parents look bewildered. They thought they were buying education.
The companies, of course, frame everything in the gentle language of engagement and outcomes. Engagement is the same word the casinos use. It’s hard not to notice that. Investors seem to believe the EdTech market will roughly double in the next several years, and the apps getting funded are, almost without exception, the ones that have mastered retention — the ones that keep small fingers tapping. Whether that’s the same thing as teaching, nobody really knows yet. The first generation raised on these tools is still in elementary school.
