Google is being strongly criticized for the departure of its well-respected co-founder of the ethical Artificial Intelligence (AI) division, amid a row over publication of a paper she had submitted for a conference. More than 1,500 Google employees and 2,000 academics, activists and industry experts have expressed concern over the exit of #TimnitGebru. She was among the most high profile black women in the top echelons of a tech company, and was known for her work on bias inherent in AI. 'Dr Gebru is one of the few people exerting pressure from the inside against the unethical and undemocratic incursion of powerful and biased technologies into our daily lives,' wrote the organizers of a petition in support of her, posted on Medium. 'This is a public service, and its importance cannot be overstated. 'Google's retaliation against Dr Gebru, and its move to silence this work, concerns us all.' The dispute arose when Gebru submitted a paper for publication about the dangers of large language models - a growing trend in AI, as technological advances means that recipes, poetry, and even news articles can be written by AI. The paper was intended for the Conference on Fairness, Accountability, and Transparency, due to be held online in March. She told CNN there was nothing unusual with the way she had submitted the paper, but Google's head of AI, Jeff Dean, said in an email to all staff that she had not allowed the required two weeks for review. 'Unfortunately, this particular paper was only shared with a day's notice before its deadline - we require two weeks for this sort of review - and then instead of awaiting reviewer feedback, it was approved for submission and submitted,' wrote Dean in his staff email. Gebru was angered by the decision to block her research, and vented in an email sent to Brain Women and Allies, a mailing list for researchers on the company's AI team known as Google Brain. Gebru described her treatment at Google as dehumanizing. (Swipe left) https://www.instagram.com/p/CIgMWtJgBr4/?igshid=hkn2qhyfktke
