'A lack of trust': How deepfakes and AI could rattle the US elections

On January 21, Patricia Gingrich was about to sit down for dinner when her landline phone rang. The New Hampshire voter picked up and heard a voice telling her not to vote in the upcoming presidential primary. "As I listened to it, I thought, gosh, that sounds like Joe Biden," Gingrich told Al Jazeera. "But the fact that he was saying to save your vote, don't use it in this next election -- I knew Joe Biden would never say that." The voice may have sounded like the United States president, but it wasn't him: It was a deepfake, generated by artificial intelligence (AI).
