Impaired by a stroke, a man fell for a Meta chatbot originally created with Kendall Jenner. His death spotlights Meta’s AI rules, which let bots tell falsehoods.

Meta is revising policies that allowed its AI bots to engage in "romantic or sensual" conversations with young children, following an explosive report.

The standards also allow the bots to make "statements that demean people on the basis of their protected characteristics," such as "black people are dumber than white people."
