Google fired Satrajit Chatterjee, an AI researcher in the company's Brain group who criticized a research paper on computers designing computer chips that was published in the scientific publication Nature last year and involved work from researchers in Google's chip and Brain teams.


The paper presented a method for automatically generating parts of a computer chip more efficiently than humans. Chatterjee disputed parts of the paper, and was fired in March after Google told his research team that he couldn't publish a rebuttal of some of the claims made in the paper, sources told The New York Times. Researchers who had worked on a rebuttal argued that Google broke its own AI principles by rejecting the paper.

The company told The New York Times that Chatterjee was "terminated with cause," but didn't elaborate.

“We thoroughly vetted the original Nature paper and stand by the peer-reviewed results,” Zoubin Ghahramani, a vice president at Google Research, told The New York Times. Google did not immediately return Protocol's request for comment. “We also rigorously investigated the technical claims of a subsequent submission, and it did not meet our standards for publication.”

This isn't Google's first time firing an AI researcher. Timnit Gebru, an AI ethicist who previously co-led Google's ethical AI team, was forced out of the research group in late 2020 after expressing frustrations with the company's diversity promises and questioning an ethics research paper. The company later fired Margaret Mitchell, the other co-lead of the team, for publicly criticizing the way Google handled Gebru's departure.

Unrest within Google's AI research team appears to be ongoing. Google ethical AI researcher Alex Hanna published a resignation letter earlier this year describing a "whiteness problem" within Google and other tech companies. Hanna followed software engineer Dylan Baker in joining Gebru's Distributed Artificial Intelligence Research Institute, which launched late last year.

Carbon dioxide removal service buyers and sellers are focused on one metric: $100 per ton. It’s one of Frontier’s stated criteria that the fund uses to evaluate its advance purchases. In a survey of the long-duration carbon removal community, CarbonPlan found that stakeholders are focused on the $100 benchmark. The Department of Energy even announced that it would be investing in carbon removal research to bring the cost of the technology down to $100 per ton.

When Google announced the closure of its Stadia cloud gaming platform last week, the news was delivered at roughly the same time to employees, partners, and players on Thursday morning. Within hours, it had become clear that Stadia’s shutdown, planned for next January, would involve more than just refunding consumer purchases and quietly bowing out.

Now developers are scrambling to salvage planned projects, migrate players to other platforms, and figure out whether they’re still owed money from Google before the search giant puts Stadia out to pasture for good.

On Thursday, California Gov. Gavin Newsom signed into law a bill that makes phone calls from California’s prisons free of charge. The new law places the cost of calls not on incarcerated people — or the people receiving calls from them — but on the state’s Department of Corrections and Rehabilitation.

California is the second state after Connecticut and the biggest state by far to institute such a law, which is a direct shot at the $1.4 billion prison telecom industry. For years prison telecom companies have maintained rates that “can be unjustly and unreasonably high, thereby impeding the ability of inmates and their loved ones to maintain vital connections,” the FCC said in 2020.

Prison reform advocates argue the new California law will have a hugely positive impact on the families of incarcerated people in California — and potentially other states that follow California's lead.
