Google AI researcher's exit sparks ethics, bias concerns

Prominent artificial intelligence scholar Timnit Gebru helped improve Google's public image as a company that elevates Black computer scientists and questions harmful uses of AI technology.

Gebru has been a star in the AI ethics world who spent her early tech career working on Apple products and got her doctorate studying computer vision at the Stanford Artificial Intelligence Laboratory.

She's co-founder of the group Black in AI, which promotes Black employment and leadership in the field. She's known for a landmark 2018 study that found racial and gender bias in facial recognition software.

Gebru had recently been working on a paper examining the risks of developing computer systems that analyze huge databases of...
