Geoffrey Hinton Leaves Google to Warn About AI's Dangers

On 1 May 2023, the New York Times published an interview with the "Godfather of AI".

Headline: 'The Godfather of A.I.' Leaves Google and Warns of Danger Ahead.

Geoffrey Hinton, 75. After ten and a half years at Google, he had resigned in order to speak.

Why He Left

"I want to talk about AI safety issues without having to worry about how it interacts with Google's business"—Hinton said clearly to the Times. "I don't want to criticise Google. Google has actually been very responsible."

Ten years earlier, in 2013, Google had acquired Hinton and his two students Alex Krizhevsky and Ilya Sutskever by buying their company DNN Research outright. The three were the authors of AlexNet (the 2012 ImageNet breakthrough). From then on, Hinton had been a Fellow at Google Brain alongside his Toronto professorship.

Sutskever later left Google to become Chief Scientist at OpenAI, where he sat at the centre of ChatGPT and GPT-4. Hinton stayed, and watched the same technology unfold in two different organisations at two different speeds.

What He Warned About

Hinton's concerns to the Times can be grouped into four levels.

Short-term — a flood of misinformation. AI-generated fake text, images, and video would soon fill the internet. Ordinary citizens would lose the ability to tell truth from fabrication.

Medium-term — job displacement. "ChatGPT isn't enough yet to displace knowledge work, but it might be soon." Intellectual labour was being automated.

Long-term — autonomous weapons and recursive self-improvement. The militarisation of AI, and the loop in which AI begins to improve itself. "There's a chance these systems could get smarter than us. A few years ago I thought it was thirty to fifty years out. I no longer think that."

Structural irreversibility. Competitive pressure—particularly between the US and China—made stopping development on safety grounds effectively impossible. Google itself had been forced to ship Bard hastily, against its preference, to keep up with OpenAI.

"I Console Myself"

The most quoted line from the interview was, "I console myself with the normal excuse: if I hadn't done it, somebody else would have."

It resembles, in cadence, the way nuclear physicists later discussed the bomb. Hinton was understanding his role in AI's development on roughly that scale.

After leaving, Hinton continued to speak through AI-safety institutes and government committees. In October 2024 he shared the Nobel Prize in Physics with John Hopfield—and his lecture, again, was largely about the existential risk of AI.

What It Changed in the Industry

Hinton's departure and warnings changed the structure of public debate.

Until then, the loudest voices warning about AI risk had been external critics, philosophers, and ethics researchers. A person at the very front of development, leaving a major company in order to warn, registered differently with governments, the press, and the lay reader.

The October 2023 Biden Executive Order, the March 2024 EU AI Act, the establishment of national AI safety institutes—none of these can be attributed to Hinton alone, but the political weather they moved through was warmer for the fact that "the person who understands AI best is sounding the alarm".

The Times piece of 1 May 2023 is remembered as the document that quietly opened the era of AI regulation.
