17 evidence-linked departures

Google's evidence-linked record spans several distinct concerns rather than a single departure wave. The dismantling of its Ethical AI team led to the departures of Timnit Gebru, Margaret Mitchell, David Baker, Alex Hanna, and Dylan Baker; Meredith Whittaker had already left in 2019 citing retaliation for organizing the Google Walkout. In 2023, Geoffrey Hinton resigned to speak freely about existential AI risk, while Jonathan Richard Schwarz says he left DeepMind because of severe concerns about concentrated power at frontier laboratories. More recent departures by Alex Turner and René Mayrhofer were tied to Google's classified Pentagon AI agreement and the safeguards governing military and surveillance uses.
