Meredith Whittaker: Why She Left Google and Her AI Critique
The 2018 Google walkout organiser who now runs Signal, and whose institute calls for bright-line rules on tech power in artificial intelligence (AI).
Meredith Whittaker helped organise the 2018 Google walkouts, left Google in July 2019, and is president of Signal, the messenger. She co-founded the AI Now Institute, and her research argues that artificial intelligence (AI) is mainly about power and who controls it, rather than machine capability. Her own account of why she left Google, and the critics who answer it, follow.
Why Meredith Whittaker Left Google
Meredith Whittaker left Google in July 2019, after she was one of the core organisers of the 2018 Google walkouts. She says she faced retaliation for that work and was told to "abandon her work" on AI ethics at AI Now. Google has not publicly conceded the retaliation she alleges, and Wikipedia doesn't record a Google response to it.
Over 20,000 employees walked out internationally, according to Wikipedia. Two things triggered the walkouts: a reported $90 million payout to Andy Rubin, who had been accused of sexual misconduct, and Google's involvement in Project Maven.
What Set Off the Walkouts
Whittaker wrote the internal petition against Google's Project Maven military AI contract. More than 3,000 Google employees signed it. Google did not renew the Maven contract afterward, according to Wikipedia.
The article Wikipedia cites on the organisers' demands is dated 1 November 2018. Wikipedia doesn't give an exact date for the walkout itself, so this section doesn't state one.
Her Account of What Followed
A VentureBeat report dated 7 June 2019 covered the departure of fellow organiser Claire Stapleton. It says Whittaker told the New York Times she was told to stop her work at New York University and AI Now after the protest. Google's side isn't recorded in the sources checked here.
Her Time at Google
Whittaker joined Google in 2006 and worked there for 13 years, according to the body text of her Wikipedia page. The infobox on the same page gives 2018 as the end year, so Wikipedia is inconsistent. This page uses 2006 to 2019 and no tighter range, with July 2019 as the departure month.
She founded Google Open Research, a group that worked on net-neutrality measurement, privacy, security and the social consequences of AI. She also co-founded M-Lab, a network measurement system.
What Meredith Whittaker Runs Now: Signal
Meredith Whittaker is president of Signal, a role Signal announced on 6 September 2022. She also sits on the board of the Signal Foundation.
Signal is a nonprofit supported by donations. The blog post says it received "a generous initial loan from Brian Acton" and aims to rely mainly on many small donors. The Signal title is dated to the 2022 announcement, and her AI Now title is as of the page read on 21 October 2026.
What Signal Says Its Costs Are
On 16 November 2023, Whittaker and Joshua Lund published "Privacy is Priceless, but Signal is Expensive" on Signal's blog. The post says Signal "reject[s] the surveillance business model." It then puts numbers on what running a messenger on those terms costs.
The post estimates that "by 2025, Signal will require approximately $50 million dollars a year to operate." At the time of the post, infrastructure cost about $14 million a year. That breaks into roughly $6 million for SMS and voice registration fees, $2.9 million for servers, $2.8 million for bandwidth, $1.3 million for storage and $700,000 for additional services.
Calling alone accounts for about 20 petabytes of outbound traffic a year, which costs roughly $1.7 million a year in bandwidth. Private contact discovery ran at its peak on nearly 600 servers costing more than $2 million a year. The post says that has since dropped to around 10 servers.
About 50 full-time employees work on Signal. About half the operating budget, roughly $19 million a year including benefits, HR, taxes and recruiting, goes to staff. The post says Signal has no investors, and it argues that no profit-minded board members push it to "sacrifice a little privacy" for growth or revenue.

Her Argument About AI: Power Rather Than Machine Capability
Her central argument about AI, made through the institute she co-founded, concerns power and political economy rather than machine capability. The AI Now bio says her research focuses on the "social implications of artificial intelligence and the tech industry." It names "a particular emphasis on power and the political economy driving the commercialization of computational technology."
The object of study is who controls computing. The sources checked for this page don't include any claim from her about machine sentience.
What the Institute Asks For
AI Now's "2023 Landscape: Confronting Tech Power," published 11 April 2023, calls for "bright-line rules and structural curbs." The report says the goal is to "ensure that it is the public, not industry, that this technology serves." Amba Kak and Sarah Myers West are listed as its authors, so this page attributes the report to the institute.
Surveillance, Facial Recognition and Whistleblowers
Signal's blog rejects the surveillance business model, and Whittaker co-wrote that post. In January 2020 she testified to the House Oversight Committee on facial recognition, and she called for a halt to the use of those technologies. See the facial recognition explainer for related background.
In June 2019 she testified to the House Science Committee. She called for whistleblower protections for tech workers.
Government and Policy Work
Lina Khan confirmed in November 2021 that Whittaker had joined the Federal Trade Commission as senior advisor on AI to the chair. Her FTC term ended at the beginning of September 2022, days before she started at Signal. AI Now's bio says she has advised the White House, the FCC, the FTC, the City of New York and the European Parliament, among others.
The Steep Cost of Capture
AI Now's contributor page lists her essay "The Steep Cost of Capture" among her contributions, dated 31 December 2021. The sources checked for this page don't include the original text, so this page only notes that the essay exists.
Co-Founding the AI Now Institute
Whittaker co-founded the AI Now Institute in 2017 with Kate Crawford, following a symposium hosted by the White House. At that symposium she was founder of Google's Open Research Group, and Crawford was a principal researcher at Microsoft Research. Today she is listed as co-founder and Chief Advisor, and she is a former Faculty Director. See the AI Now Institute explainer for more on the group.
The institute says it "does not currently take funding from corporate donors." It says its current funding comes from foundations. Critics raise that point in the final section below.
Her Other Roles
She was formerly Minderoo Research Professor at New York University. Wikipedia doesn't publish start or end dates for that professorship. TIME named her to its 100 most influential people in AI in 2023, and she joined the board of Hubert Burda Media in July 2025.

Where She Disagrees With the AI-Doom Camp
NBC News published an article on 30 May 2023 that AI Now has reposted on its own site. The excerpt describes Whittaker as president of Signal and chief adviser to AI Now. It says she mocked an extinction-risk statement, framing it as tech leaders overpromising their product.
That is NBC's characterisation of her reaction, not a verbatim quote from her. This page doesn't quote her on the point for that reason. The repost is linked in the sources below.
What Critics Say Back
The retaliation claim is her account alone. Google has not publicly conceded it, and Wikipedia doesn't record a Google response.
Signal's cost figures cut both ways. By her own numbers, a privacy-respecting messenger needs about $50 million a year and about 50 full-time staff. Critics can read those figures as an argument that donation-funded independence is fragile.
Her reaction to extinction-risk arguments, as NBC reports it, is a stated position. It isn't a finding about whether the risk is real. Critics on the other side of that debate can point to the difference.
There is also a structural point. She spent 13 years inside Google. Her institute's independence rests on foundation money rather than corporate money. Foundation money is a different dependency from corporate money, rather than none.
What Remains Unsettled
Several details here are unconfirmed. Walkout headcounts above 20,000 appeared in search results but weren't confirmed in a source, so this page uses "over 20,000 employees" only. The exact day she left Google isn't in any source checked, so this page gives July 2019. A widely reported 2023 remark about Geoffrey Hinton couldn't be confirmed, so this page doesn't quote it. Her salary at Signal isn't in any source checked here, and this page doesn't estimate it.
To judge her AI argument directly, start with the 2023 Landscape report linked in the sources. For how her work fits the wider backlash against AI, read the guide to who is fighting AI.
