Borders between countries are often dangerous, violent places. From the sands of the Sahel to the islands of the Mediterranean, borders allow governments to define who can enter a country – often deciding whether a person can find refuge or is left behind.

Increasingly, borders are also spaces for governments and private companies to test new technology. But how is that technology being used? And what impact is it having for people on the move?

Petra Molnar’s new book The Walls Have Eyes: Surviving Migration in The Age of Artificial Intelligence offers a sweeping portrait of how new tech, from surveillance drones to lie detection software, is transforming borders around the world.

A lawyer and anthropologist, Petra specializes in migration and human rights. She co-runs the Refugee Law Lab at York University and is a faculty associate at Harvard’s Berkman Klein Center for Internet and Society.

Just Security Podcast host Paras Shah recently sat down with Petra to discuss the book, which is available now from The New Press and wherever books are sold.
