The tech writer and podcaster Bridget Todd was sure she’d never get attached to A.I. chatbots. She was suspicious of the companies behind them, and when she saw articles popping up about people who said they loved their bots, she said she found their situations sad and potentially dangerous. Besides, Bridget didn’t have an empty hole in her life to fill. She had a supportive human partner. She had friends and a tight knit family. But then Bridget’s life started to unravel. After the death of her parents, she was flooded with fear, grief and a kind of isolation she was not prepared for. That’s when she started telling A.I. what she couldn’t tell the people in her life. Its responses filled a void. In this episode of “Modern Love,” Bridget tells its host, Anna Martin, what happened when the boundary between human and digital companion got fuzzy, and what life looks like for her on the other side.  Bridget’s audio book, “Love at First Prompt: AI and the Future of Intimacy,” is out now.
