Meta AI Chief Yann LeCun Expresses Skepticism About AGI and Quantum Computing


Meta’s chief AI scientist, Yann LeCun, recently shared his views on the future of artificial intelligence (AI) and quantum computing, revealing a skeptical stance on both fronts. His comments came during an event marking the 10-year anniversary of Meta’s Fundamental AI Research team.

Key Points from LeCun’s Perspective:

  • LeCun believes current AI systems are decades away from achieving any form of sentience or common sense.
  • He contrasts Nvidia CEO Jensen Huang’s view, who predicts AI will rival human intelligence in less than five years.
  • LeCun suggests that society is more likely to develop “cat-level” or “dog-level” AI before achieving human-level intelligence.
  • He criticizes the current focus on language models and text data, stating they are insufficient for advanced AI development.
  • LeCun and other Meta AI executives are researching AI models that work with various data types, including audio, image, and video.
  • He is also skeptical about the practical relevance and feasibility of quantum computing.

Meta’s AI Research and Future Directions:

Meta’s AI research includes developing software for augmented reality applications, like teaching tennis using AR glasses. These applications require AI models that can process three-dimensional visual data along with text and audio. LeCun emphasizes the need for multimodal AI systems, which he believes represent the next frontier in AI development.

The AI Hardware Landscape:

Nvidia, known for its graphics processing units (GPUs), has been a significant beneficiary of the generative AI trend. Meta used 16,000 Nvidia A100 GPUs to train its Llama AI software. LeCun acknowledges the current dominance of GPUs but foresees the emergence of specialized neural, deep learning accelerators in the future.

Quantum Computing: A Fascinating but Uncertain Field:

LeCun’s skepticism extends to quantum computing, a field that tech giants like Microsoft, IBM, and Google are heavily investing in. He questions the efficiency of quantum computing compared to classical computers and its practical relevance in the foreseeable future. Mike Schroepfer, Meta’s senior fellow and former tech chief, shares LeCun’s view, considering quantum technology’s long time horizon as irrelevant to current AI developments.


LeCun’s insights provide a grounded perspective on the hype surrounding AI and quantum computing. As Meta continues to explore the potential of AI in various applications, his cautious approach highlights the importance of realistic expectations and the need for continued innovation in both AI and computing hardware.
