NPR's Juana Summers talks with software engineer Daniel Patt about his website "From Numbers to Names," which uses artificial intelligence to find photos of victims and survivors of the Holocaust.

Most survivors of World War II's Nazi concentration camps are now in their 80s and 90s, and soon there will be no one left who experienced the horrors of the Holocaust firsthand -- no one to answer questions or bear witness to future generations. But as we first reported two years ago, a new and dramatic effort is underway to change that by harnessing the technologies of the present and the future. To keep alive the ability to talk to -- and get answers from -- the past. Our interview with Holocaust survivor Aaron Elster, who spent two years of his childhood hidden in a neighbor's attic, was unlike any interview we have ever done. "Aaron, tell us what your parents did before the war," Stahl asked Elster. "They owned and operated a butcher shop," Elster said. It wasn't the content of the interview that was so unusual. "Where did you live?" Stahl asked. "I was born in a small town in Poland called Sokolów Podlaski," Elster said. It's the fact that this interview was with a man who was no longer alive. Aaron Elster died four years ago.

This content can also be viewed on the site it originates from. In "His Master's Voice," a 1968 sci-fi novel by the Polish writer Stanisław Lem, a team of scientists and scholars convened by the American government try to decipher a neutrino signal from outer space. They manage to translate a fragment of the signal's information, and a couple of the scientists use it to construct a powerful weapon, which the project's senior mathematician fears could wipe out humanity. The intention behind the message remains elusive, but why would an advanced life-form have broadcast instructions that could be so dangerous? Late one night, a philosopher on the team named Saul Rappaport, who emigrated from Europe in the last year of the Second World War, tells the mathematician about a time--"the year was 1942, I think"--when he nearly died in a mass execution.

Fox News media analyst Howard Kurtz joins'America Reports' to discuss the widely criticized CBS '60 Minutes' segment. A widely criticized "60 Minutes" report focusing on Florida Republican Gov. Ron DeSantis is the latest example of a mainstream media attack on the potential 2024 White House hopeful. Despite the Sunshine State's robust economy and a strong response to the coronavirus pandemic (Florida currently has the the 27th-most coronavirus deaths per capita despite being the third-most populous state in the Union), DeSantis has come under fire in the press for everything from partnering with the Publix grocery store chain on vaccinations, to getting shots to Holocaust survivors, to accusations of cooking the books, to keeping the state largely open during the pandemic, to running afoul of a Florida data scientist who was later arrested for hacking a state computer system. "This is partisan corporate media and I think at this point these people ... they're basically ambulance chasers with a microphone," DeSantis said on "Fox & Friends" Tuesday. We know they're lying, they know that we know that they're lying, and yet they lie and they lie and they lie." DeSantis, a strong ally of former President Donald Trump, is a potential contender for the 2024 Republican presidential nomination. In the "60 Minutes" segment, which aired Sunday, correspondent Sharyn Alfonsi alleged DeSantis gave Publix lucrative rights to vaccine distribution in response to a $100,000 donation to his PAC. However, Publix and DeSantis vigorously disputed the piece's recycled narrative, and critics noted Publix was a natural fit for vaccine partnership given its more than 800 locations in the state. "That's a fake narrative," DeSantis told CBS News. "I met with the county mayor, I met with the administrator, I met with all the folks at Palm Beach County and I said, 'Here's some of the options: We can do more drive-thru sites, we can give more to hospitals, we can do the Publix.'

A team of researchers from the University of Southern California are working to immortalize the stories of Holocaust survivors while they still can. Using a combination of augmented and virtual reality, as well as artificial intelligence, they've created holograms of survivors, many aged well into their 90s, that museum visitors can interact with and ask questions. Holocaust survivor Pinchas Gutter (pictured) was re-created as a hologram as part of the'New Dimensions in Testimony' project created by USC's Shoah Foundation Researchers from the University of Southern California's Shoah Foundation are preserving Holocaust survivors' stories using holograms. Subjects sit under a dome that has more than 1,000 lights, capturing every angle. That footage is used to construct a hologram of the Holocaust survivor.

Pinchas Gutter goes out of his way to find me biscuits. In a sun-baked living room in his north London home, he opens a packet of Rich Tea, sits down and tells me about the Holocaust. Gutter was seven years old when the second world war broke out. He lived in the Warsaw ghetto for three and a half years, took part in its uprising, survived six Nazi concentration camps – including the Majdanek extermination camp – and lived through a death march across Germany to Theresienstadt in occupied Czechoslovakia. "Remembrance is the secret of redemption, while forgetting leads to exile," he says, quoting Baal Shem Tov, the founder of Hasidic Judaism.

We discuss philosophical and ethical issues that arise from a dialogue system intended to portray a real person, using recordings of the person together with a machine agent that selects recordings during a synchronous conversation with a user. System output may count as actions of the speaker if the speaker intends to communicate with users and the outputs represent what the speaker would have chosen to say in context; in such cases the system can justifiably be said to be holding a conversation that is offset in time. The autonomous agent may at times misrepresent the speaker's intentions, and such failures are analogous to good-faith misunderstandings. The user may or may not need to be informed that the speaker is not organically present, depending on the application.
