How AI is helping to trace children who went missing during Argentina’s military dictatorship 40 years ago

If a baby was taken from their parents four decades ago during Argentina’s military dictatorship, what would that person look like today?

Argentine publicist Santiago Barros has been trying to answer that question using artificial intelligence to create images of what the children of parents who disappeared during the dictatorship might look like as adults.

Almost every day, Barros uploads these images to an Instagram account called iabuelas, which is a portmanteau in Spanish for artificial intelligence, or IA, and grandmother, or abuela – taken from the well-known activist group Grandmothers of Plaza de Mayo that searches for missing children.

“We have seen the photos of most of the disappeared, but we don’t have photos of their children, of those children who were stolen”, Barros said. “It struck me that these people did not have a face”.

During Argentina’s bloody dictatorship from 1976 to 1983, military officials carried out the systematic theft of babies from political dissidents who were detained or often executed and disposed of without a trace. The babies were often raised by families linked to the dictatorship, or those ideologically aligned with it, as if they were their own.

Using an app called Midjourney, Barros combines photos of the disappeared fathers and mothers from the public archive of the Grandmothers website, creating images of what the faces of their children might look like as adults today. For each combination, the app shows two female and two male possibilities. Barros then chooses the image of each gender that seems most realistic.
