The US has spent billions of dollars on border surveillance using towers that increasingly utilize AI. According to MIT Technology Review AI, the system was intended to accelerate response times to border crossings.

The publication's investigation, based on its synopsis, examined death cases near such towers and concluded that the system is failing to deliver on its promised task. Available materials lack details on individual cases, the scale of the problem, or specific technologies.

The story's significance lies in testing the practical effectiveness of expensive surveillance infrastructure, not just the claimed capabilities of AI. The full text of the investigation is needed to assess the causes of failures and official actions.
