The debate over Artificial General Intelligence, or AGI, is back in focus as some of the world’s most influential figures publicly disagree on whether such a system is even possible.
The latest exchange involves Google DeepMind CEO Demis Hassabis and AI pioneer Yann LeCun, with Tesla and X owner Elon Musk stepping in to support Hassabis. The discussion matters as companies like OpenAI and Google push toward more capable AI systems.
Yann LeCun, a Turing Award winner and former head of Meta AI, reignited the discussion during a recent podcast appearance. He argued that the common idea of general intelligence is fundamentally flawed. According to LeCun, human intelligence is not general but rather specific, shaped by physical interaction with the real world. He described AGI as an illusion and suggested people overestimate their own cognitive flexibility.
Moreover, LeCun suggested that humans are typically oblivious to many problems surrounding them and cannot solve everything they face. From his viewpoint, this limitation challenges the idea of a single system that could rival or surpass human intelligence in every aspect.
Demis Hassabis strongly disagreed with LeCun’s assessment, calling it “plain incorrect.” He argued that LeCun was “confusing general intelligence with universal intelligence.” Hassabis explained that general intelligence does not mean being able to do everything instantly.
“The point about generality is that in theory, in the Turing Machine sense, the architecture of such a general system is capable of learning anything computable given enough time and memory (and data), and the human brain (and AI foundation models) are approximate Turing Machines,” he said.
The discussion also caught Tesla CEO Elon Musk’s attention, who resoundingly supported Hassabis's comments and reshared his thoughts. Musk's reaction was surprising, given his long-standing involvement in AI research and his role as one of OpenAI’s founders.
AGI refers to a hypothetical form of artificial intelligence that can acquire knowledge, reasoning, and adapt to various fields instead of performing well at one specific area. Companies like OpenAI and Google are still working on the technology, regarding it as a way to transform various fields. The tech giants believe AGI could unlock breakthroughs across science, medicine, and technology.
The public argument highlights the uncertainty around the future of artificial intelligence. The fact that even the most renowned specialists have varied opinions hints at why AGI is still one of the most conflicting concepts in today’s technology.
