Timnit Gebru—a giant in the world of AI and then co-lead of Google’s AI ethics team—was pushed out of her job in December. Gebru had been fighting with the company over a research paper that she’d coauthored, which explored the risks of the AI models that the search giant uses to power its core products—the models are involved in almost every English query on Google , for instance. The paper called out the potential biases (racial, gender, Western, and more) of these language models, as well as the outsize carbon emissions required to compute them. Google wanted the paper retracted, or any Google-affiliated authors’ names taken off; Gebru said she would do so if Google would engage in a conversation about the decision. Instead, her team was told that she had resigned. After the company abruptly announced Gebru’s departure, Google AI chief Jeff Dean insinuated that her work was not up to snuff—despite Gebru’s credentials and history of groundbreaking research . The backlash was immediate. Thousands of Googlers and outside researchers leaped to her defense and charged Google with attempting to marginalize its critics , particularly those from underrepresented backgrounds. A champion of diversity and equity in the AI field, Gebru is a Black woman and was one of the few in Google’s research organization. “It wasn’t enough that they created a hostile work environment for people like me [and are building] products that are explicitly harmful to people in our community. It’s not enough that they don’t listen when you say something,” Gebru says. “Then they try to silence your scientific voice.” In the aftermath, Alphabet CEO Sundar Pichai pledged an investigation; the results were not publicly released, but a leaked email recently revealed that the company plans to change its research publishing process, tie executive compensation to diversity numbers, and institute a more stringent process for “sensitive employee exits.” In addition, the company appointed engineering VP Marian Croak to oversee the AI ethics team and report to Dean
