How churches use data and AI as engines of surveillance
On a Sunday morning in a Midwestern megachurch, worshippers step through sliding glass doors into a bustling lobby—unaware they’ve just passed through a gauntlet of biometric surveillance. High-speed cameras snap multiple face “probes” per second, before passing the results to a local neural network that distills these images into digital fingerprints. Before people find their seats, they are matched against an on-premises database—tagged with names, membership tiers, and watch-list flags—that’s stored behind the church’s firewall.
This hypothetical scene reflects real capabilities increasingly woven into places of worship nationwide, where spiritual care and surveillance converge in ways few congregants ever realize.
Where Big Tech’s rationalist ethos and evangelical spirituality once mixed like oil and holy water, now they’re combining to redraw the contours of community and pastoral power in modern spiritual life. Read the full story.

One more thing
Responsible AI has a burnout problem
Margaret Mitchell had been working at Google for two years before she realized she needed a break. Only after she spoke with a therapist did she understand the problem: she was burnt out.
Mitchell, who now works as chief ethics scientist at the AI startup Hugging Face, is far from alone in her experience. Burnout is becoming increasingly common in responsible AI teams.
All the practitioners MIT Technology Review interviewed spoke enthusiastically about their work: it is fueled by passion, a sense of urgency, and the satisfaction of building solutions for real problems. But that sense of mission can be overwhelming without the right support. Read the full story.
