MIT Technology Review's groundbreaking investigation reveals that the US's virtual border wall surveillance towers have failed to prevent deaths, leading to a humanitarian crisis, and the organization is hosting a roundtable to examine these failures.
<p>The US has spent billions building a “virtual wall” of surveillance towers along its southern border over the past 25 years, promising they will help detect and apprehend border crossers and save lives. But a <strong><a href="https://www.technologyreview.com/2026/09/21/1144166/border-towers-surveillance-investigation/">groundbreaking investigation by <em>MIT Technology Review</em></a></strong> has documented over a thousand people who moved through areas watched by these towers without being reached or apprehended, and who ultimately died there. Some were even under the watch of newly installed AI-powered towers designed to spot people automatically.</p>
<p>Our findings reveal a humanitarian crisis more visible than previously known, and repeated failures of the virtual wall’s basic security promise. Join MIT Technology Review editors and reporters for a conversation examining the failures of border surveillance technology and uncovering the stories of the people who die in the borderlands.</p>
