The rise of 'grief tech': AI is being used to bring the people you love back from the dead

In 2016, James Vlahos discovered that his father was dying from terminal lung cancer. Painfully aware that their time together was running out, Vlahos rushed to gather memories while he still could, recording his father's life story; everything from childhood memories to his favourite sayings, songs and jokes. Once transcribed, these recordings filled 200 single-spaced pages. "It was a great, but inert resource, and I longed for something interactive. So I spent nearly a year programming a chatbot replica of my father: the'Dadbot,'" said Vlahos.
