Over the past 25 years, the United States has invested billions of dollars in building a virtual wall of surveillance towers along its southern border, according to MIT Technology Review. These towers, designed to monitor and detect unauthorized crossings, have repeatedly failed to apprehend many individuals moving through these areas.

MIT Technology Review reported that hundreds of people have crossed areas under surveillance without being detected or stopped, ultimately leading to numerous deaths. This includes incidents under newly installed AI-powered towers that were intended to automatically identify people, but still failed to prevent fatalities.

For Japanese investors and markets, this investigation highlights the challenges in deploying advanced surveillance technologies effectively, a cautionary note for sectors involved in AI and border security solutions.
