MIT Technology Review is reporting that the United States has spent billions of dollars over the past 25 years building a "virtual wall" of surveillance towers along its southern border, with the promise that the technology would help detect and apprehend border crossers and save lives.

It said a groundbreaking investigation by the outlet documented more than a thousand people who moved through areas watched by these towers without being reached or apprehended, and who ultimately died there. Some of those people were under the watch of newly installed AI-powered towers designed to spot people automatically, it said.

MIT Technology Review said its findings reveal a humanitarian crisis more visible than previously known, along with repeated failures of the virtual wall's basic security promise.

The outlet said it held a conversation examining the failures of border surveillance technology and uncovering the stories of the people who die in the borderlands. The session featured editor in chief Mat Honan, senior AI reporter James O'Donnell and senior features and investigations reporter Eileen Guo, and was recorded on September 28, 2026.

MIT Technology Review also said it published related stories, including an examination of why the billions spent on border surveillance cannot catch people before they die, a report on how it made the first comprehensive map of deaths along the US border's "virtual wall," and four ways to address the failures it found along that wall.
