How a man kept his father's memory alive using artificial intelligence

That is, he talks to the version of his father that lives on through Dadbot, an artificially intelligent chatbot he designed to retain his dad's experiences and personality. Vlahos documented his experience creating the chatbot in Wired magazine's August cover story, "Dadbot." The bot operates through Facebook Messenger, and it carries out conversations using John Vlahos's own stories and words. Before John Vlahos died -- at home in his sleep at the age of 81, surrounded by family on Feb. 17 -- he was able to interact with the bot himself.
