The people who built the engagement machines at Google and Facebook sit down to explain how it works. They engineered your compulsion on purpose and sold your attention by the pound. The confession is more convincing than the dramatization wrapped around it.

A parade of Silicon Valley engineers and executives sit down to confess. They built the recommendation engines, the notification systems, and the infinite scroll. Now they want you to know what they did. Jeff Orlowski’s documentary frames the attention economy as a deliberate machine that turns human behavior into a product sold to advertisers. The film is not about screen time. It is about a business model that profits from your manipulation and treats your psychology as inventory.

Tristan Harris anchors the testimony as the former Google design ethicist who walks through how products engineer compulsion. He speaks with the calm of a man describing a crime he helped commit. Tim Kendall, the former Facebook executive and Pinterest president, admits he cannot put his own phone down at the dinner table. Guillaume Chaslot explains the YouTube recommendation algorithm he worked on and how it learns to feed outrage because outrage holds attention. These are not whistleblowers from the outside. They are the architects, and Orlowski lets their discomfort do the persuading.

Orlowski and co-writers Davis Coombe and Vickie Curtis cut the interviews against a dramatized subplot about a teenage boy radicalized by his feed. The reenactments visualize the algorithm as three actors operating a control room inside the phone, pulling levers to maximize engagement. This device flattens the argument into a literal puppet show and undercuts the credibility the interviews build. The strongest sequences abandon the fiction and stay with the engineers and the data. Editing the confessions into a mounting accumulation is where the film earns its alarm, and the Emmy for picture editing recognizes that rhythm.

The documentary works best as a primer for people who have never questioned why the app never ends. It names the mechanism, identifies who profits, and refuses to pretend the harm is accidental. The dramatizations talk down to the audience and the warnings tip into the apocalyptic. The interviews do not need the help. When the men who built the machine tell you to be afraid of it, the machine has already told you everything you need to know.
