For years, the AI industry has followed a set of guidelines known as “scaling laws,” OpenAI researchers outlined them in the seminal 2020 paper, “Scaling Laws for Neural Language Models.” which suggest that AI performance improves with increased scale specifically, larger model parameters, more data, and more compute power. This principle has driven significant investments in data centers that allow AI models to process and learn from vast amounts of information. However, some AI experts, including Meta’s chief AI scientist Yann LeCun, are now challenging this doctrine, arguing that scaling alone does not necessarily lead to smarter AI as reported by Business Insider Africa.
LeCun points out that simply feeding AI more data and computational power will not automatically create superintelligence. He emphasizes that many of the most interesting problems in AI do not scale well. He believes the mistake lies in assuming that systems that work well for simple tasks can be scaled up to solve more complex problems. According to LeCun, the current breakthroughs in AI are often based on relatively simple systems, which can work well on simpler tasks but do not necessarily perform better when applied to more complex, real-world scenarios.

LeCun suggests that the real key to advancing AI lies in a different approach—training AI to understand the physical world, reason logically, and learn quickly. Unlike current large language models, which rely on recognizing patterns in data, LeCun advocates for AI that can predict how actions affect the world and solve problems with common sense and persistence. This world-based learning model, according to LeCun, would provide AI with the type of cognition needed to tackle complex, uncertain real-world problems.
The slowing pace of AI advancements in recent years may also be partly due to the limitations of scaling. As the availability of high-quality public data dwindles, AI models are becoming less effective at learning new tasks. This has led to growing frustration among experts, including Alexandr Wang, CEO of Scale AI, who sees scaling as the biggest question facing the industry, and Aidan Gomez, CEO of Cohere, who has called it a misguided approach.
LeCun’s views are part of a broader shift in AI research, where experts are looking beyond raw data processing and focusing more on developing AI that can think, reason, and interact with the world in ways that mimic human intelligence. The goal is to create systems that can adapt, learn quickly, and understand the world at a deeper, more practical level, beyond simply predicting the next step in a sequence of data.
