A Respected Voice Sounds the Alarm
In a move that has caught the attention of the global AI community, Geoffrey Hinton, a pioneering researcher in artificial intelligence and the renowned “Godfather of AI,” has left his role at Google.
The departure allows Hinton to speak more openly about the potential dangers of the technology he helped create. With high-profile figures like Elon Musk and Noam Chomsky already expressing concerns, Hinton’s decision has added weight to the ongoing debate surrounding AI’s risks.

Hinton’s Groundbreaking Work
Hinton’s work on deep learning and neural networks over his decades-long career has been foundational to modern AI technology. His departure comes amidst a surge in AI advancements, with companies like Microsoft-backed OpenAI releasing their latest AI model, GPT-4, and Google investing in their own competing tools like “Bard.”
In recent interviews, Hinton has described the potential dangers of AI chatbots as “quite scary” and warned of “bad actors” who may misuse AI for nefarious purposes, such as manipulating elections or inciting violence. Watch Hinton speak with Will Douglas Heaven, MIT Technology Review’s senior editor for AI, at EmTech Digital.
Independence from Google
The 75-year-old researcher has chosen to retire from Google so he can discuss AI safety issues without concern for how it may intersect with the tech giant’s interests.
Although Hinton has maintained that Google has acted responsibly regarding AI, he believes his comments will be more credible now that he is no longer an employee.
Debating AI’s Dangers: Present vs. Future
The ongoing debate about AI’s potential risks centers on whether the primary dangers lie in the future or are already present. Hypothetical existential risks from superintelligent computers contrast with concerns about currently deployed automated technology that can cause real-world harm.
AI’s role in amplifying existing societal biases and exacerbating inequality is a topic of particular concern among researchers.
Alondra Nelson, former leader of the White House Office of Science and Technology Policy, emphasizes the importance of a democratic and non-exploitative future with technology. The conversation around AI’s dangers must include AI experts, developers, and the public, she says.
Turing Award Winners Voice Concerns
Hinton’s fellow Turing Award winners, Yoshua Bengio and Yann LeCun, have also expressed their concerns about the future of AI. Bengio, a professor at the University of Montreal, signed a petition calling for a six-month pause on powerful AI system development, while LeCun, a top AI scientist at Facebook parent Meta, has taken a more optimistic approach.
As AI continues to advance rapidly, the discussions surrounding its potential dangers and ethical considerations will only grow more critical. Hinton’s departure from Google and his determination to speak openly about AI’s risks will likely inspire more experts to join the conversation.
The Surprising Revelation
Geoffrey Hinton’s awe at the capabilities of advanced language models like GPT-4 has led him to raise public awareness about the potential risks associated with the technology he helped bring to life.
At 75, Hinton feels his age has made it difficult for him to engage in detailed technical work, but he’s eager to focus on the “more philosophical work” related to AI’s possible dangers.
Unshackled from Google
Hinton believes that leaving Google will allow him to discuss AI safety issues without the self-censorship he would have to exercise as a Google executive. Despite his concerns about AI, he insists that he harbors no ill will towards the tech giant and wants to speak about the company’s positive aspects, which will be more credible once he’s no longer employed there.
The Changing Landscape of AI Intelligence
The advent of large language models, particularly GPT-4, has made Hinton realize that machines are developing intelligence far beyond what he initially anticipated. He now sees artificial neural networks as surpassing biological ones in certain aspects, a change that he finds both fascinating and terrifying.
The Case for AI’s Potential Superiority
Hinton argues that large language models, despite their smaller size compared to human brains, possess a learning algorithm that is more efficient than ours. Moreover, he highlights the concept of “few-shot learning,” in which pretrained neural networks can learn new tasks extremely quickly, rivaling human learning speeds.
As for the issue of AI-generated hallucinations, Hinton contends that confabulation is a natural part of human conversation and that AI simply needs more practice to generate more accurate responses.
Communication Advantages and New Forms of Intelligence
Hinton envisions a future where neural networks can communicate and share experiences seamlessly, leading to a more advanced form of intelligence. He believes that there are now two types of intelligence in the world: animal brains and neural networks, with the latter representing a new and superior form of intelligence.
The implications of this new form of intelligence remain divisive, with opinions ranging from optimistic to apocalyptic. Hinton himself leans towards a cautious stance, expressing fear that these AI tools could potentially manipulate or harm humans who are unprepared for such advanced technology.
