There are more than 800 surveillance towers located along U.S. borders, a number that is expected to triple in the next decade. These towers, according to a government accountability report, “detect items of interest, such as people.” But interest can be fickle. As part of “Dying on Camera,” a sprawling package of features co-published by the MIT Technology Review and Times of San Diego, Lillian Perlmutter reports on the death of Graciela Gómez Hernández, one among hundreds of migrants whose final moments seem as though they should have been witnessed. “The proximity of so many deaths to high-resolution cameras leaves two distinct possibilities,” Perlmutter writes. “Either the system didn’t detect these people in distress, or it did detect them—and officials offered no response. “

Surveillance towers have proliferated in recent years, as contractors added newer camera systems that use artificial intelligence to distinguish border-crossers from other people and animals, and track their movements, at an overall cost of more than a billion dollars. Yet as the cameras scan the terrain, migrants continue to die in plain sight. 

In this story for MIT Technology Review, Sara Harrison explores the field of social robotics and the growing use of robot companions as therapy for autistic and other neurodivergent kids. These playful machines show promise: Research suggests that they can help children practice social skills and offer something overworked therapists and exhausted parents can’t—a patient companion, available 24/7. But Harrison also reports on their limitations and risks. Does this approach truly work? What about all the data gathered on the child? And what happens when a robot friend suddenly stops working and “dies”? A fascinating and unsettling look at tech that has moved into the most intimate corners of a family’s home.

While Moxie found herself in more and more people’s homes, Embodied still struggled to make money. In 2024, the company announced it would cease operations. Its robots—which depended on external servers that the company could no longer pay for—would descend into a deep slumber. 

Videos of bereft children who seemed to have become deeply attached to the blue bot began to circulate online. “I don’t want her to leave,” wailed one child in a TikTok video. Desperate parents posted on TikTok, Instagram, and Reddit looking for solutions. “My autistic child is devastated and I’m pissed,” wrote one parent. “Hope Embodied gives us a couple days to say goodbye,” wrote another.

Midway through Boyce Upholt’s mind-boggling dispatch, one of his sources sums up the central challenge of the Gulf Coast canid: “Why is there not just a simple explanation for what this thing is?” The “wolfy coyotes” of southeastern Texas hold genetic traces that may link them to red wolves, which were declared extinct in the wild in 1980. But a lack of data makes it challenging to define the species—or, for that matter, to determine whether a private company has cloned the red wolf or something else entirely. Upholt doesn’t deal in simple explanations; the pleasure, here, is in the complexity.

The concept of a “species” is less sturdy than your high school biology teacher might have led you to believe. The most familiar definition is that a species consists of animals that can produce fertile offspring. But that’s a rule various species of canids violate all the time; it’s long been clear that North America’s soup of Canis genes is something less like a family tree and more like a river—one that’s broken by islands and sandbars into many braided channels that split and merge and re-split.
