Meta’s AI chief: LLMs will never reach human-level intelligence

In the fast-paced world of artificial intelligence, the buzz surrounding artificial general intelligence (AGI) continues to captivate tech enthusiasts and experts alike. High-profile figures like Nvidia’s CEO Jensen Huang, AGI pioneer Ben Goertzel, and visionary Elon Musk have recently made bold predictions about the imminent arrival of AGI, with timelines ranging from three to five years.

However, amidst the optimism, skepticism looms. Yann LeCun, Meta’s chief AI scientist and a respected figure in the field, challenges the very notion of AGI. LeCun argues that human intelligence is far from being truly general, preferring to focus on achieving “human-level AI” instead. At a recent event in London, he highlighted four fundamental cognitive challenges that current AI systems struggle with, including reasoning, planning, memory, and understanding the physical world.

LeCun’s critique extends to large language models (LLMs), such as Meta’s LLaMA and OpenAI’s GPT-3, which are heavily reliant on text data. While impressive in their language capabilities, LLMs fall short in truly grasping the complexities of human intelligence and the physical world, according to LeCun.

Proposing an alternative approach, LeCun advocates for “objective-driven AI,” where systems are designed to achieve specific goals through interactions with the physical world, rather than just text-based learning. By training on a variety of sensory data, these systems develop a robust understanding of their environment, enabling them to plan and execute tasks effectively.

LeCun’s vision aims to overcome the limitations of current AI models and pave the way for machines to eventually surpass human intelligence. While acknowledging the journey ahead, he cautions against overly optimistic timelines, contrasting with Musk’s bold projections.

As the realm of artificial intelligence continues to evolve, discussions around the nuances of achieving true intelligence and the role of diverse data sources in machine learning highlight the multifaceted nature of the AI landscape.
