Google Plans to Double AI Ethics Research Staff

"Being responsible in the way that you develop and deploy AI technology is fundamental to the good of the business," Ms. Croak said. "It severely damages the brand if things aren't done in an ethical way." Google announced in February that Ms. Croak would lead the AI ethics group after it fired the division's co-head, Margaret Mitchell, for allegedly sharing internal documents with people outside the company. Ms. Mitchell's exit followed criticism of Google's suppression of research last year by a prominent member of the team, Timnit Gebru, who says she was fired because of studies critical of the company's approach to AI. Mr. Pichai pledged an investigation into the circumstances around Ms. Gebru's departure and said he would seek to restore trust.
