Photo: Carsten Koall/Getty Images Google CEO Sundar Pichai apologized Wednesday for the company's handling of the departure of AI ethics researcher Timnit Gebru and said he would investigate the events and work to restore trust, according to an internal memo sent companywide and obtained by Axios. Why it matters: Gebru's exit has provoked anger and consternation within Google as well as in academic circles, with thousands of people signing an open letter urging Google to reexamine its practices. In the note, Pichai acknowledged the depth of the damage done by the company's actions and said the company would look at all aspects of the situation, but stopped short of saying the company made a mistake in removing Gebru.
