Timnit Gebru

Timnit Gebru (born 1983 in Addis Ababa) is an Ethiopian-born computer scientist of Eritrean descent who emigrated to the United States as a teenager and earned her PhD at Stanford under Fei-Fei Li. Her collaboration with Joy Buolamwini on Gender Shades (2018) — showing commercial facial recognition failed most on darker-skinned women — became one of the most influential audits in AI history and helped push major vendors to pause face-recognition sales.

The Google firing

As co-lead of Google’s Ethical AI team, Gebru co-authored “On the Dangers of Stochastic Parrots” with Emily M. Bender and others — a paper questioning ever-larger language models on grounds of bias, cost, environmental footprint, and their inability to understand what they generate. Google demanded a retraction; Gebru refused without discussion, and in December 2020 was abruptly told the company was “accepting her resignation.” Thousands of Googlers and academics signed protests, and her ouster became a defining scandal of corporate AI research.

Exactly one year later she launched the Distributed AI Research Institute (DAIR), an independent, community-rooted lab documenting AI’s effects on marginalized groups, deliberately funded outside Big Tech. She has since co-developed the “TESCREAL” critique with philosopher Émile Torres, arguing that utopian AGI ideologies function as a distraction from present, measurable harms — exploited data workers, biased systems, and concentrated corporate power.

Gebru does not argue that machines will destroy humanity; she argues the companies building them are harming people now. That distinction has made her both a hero of the accountability movement and a persistent irritant to boosters and doomers alike.
