Yann LeCun Says Computer Science Degrees Alone May Not Be Enough in the Age of Ai
Meta’s chief AI scientist Yann LeCun, widely regarded as one of the founding figures of modern artificial intelligence, has sparked a debate by questioning the long-term value of computer science degrees if students fail to build strong foundations. Speaking recently, LeCun argued that graduates risk becoming irrelevant if they focus on short-term, trendy skills instead of deep, transferable knowledge.
Context: Skills vs Foundations in a Fast-Changing Tech World
LeCun’s remarks come at a time when AI tools are rapidly reshaping programming, software development, and engineering roles. According to a Business Insider report, LeCun warned that many computer science (CS) students may struggle to adapt to future technological shifts if their education lacks rigorous training in mathematics and foundational sciences.
In an emailed statement to the publication, LeCun said that CS majors who only complete the minimum required math courses could find themselves ill-prepared for major changes in technology.
Why Math and Engineering Matter
During an appearance on The Information Bottleneck podcast, LeCun stressed the importance of learning concepts with a “long shelf life.” He emphasised mathematics, modelling, and subjects that connect abstract theory with real-world systems.
LeCun noted that engineering disciplines—such as electrical or mechanical engineering—often provide this depth. In the US, he explained, engineering students typically study Calculus 1, 2, and 3, while many CS programmes allow students to graduate with only introductory calculus.
“In computer science, you can get away with just Calculus 1,” LeCun said, adding that this is often insufficient for understanding the deeper principles behind emerging technologies.
A Provocative but Clarified View
LeCun jokingly described himself as “a computer science professor arguing against studying computer science,” but later clarified his position. He stressed that he was not advising students to avoid CS degrees altogether.
Instead, he encouraged CS students to maximise their exposure to foundational subjects, including mathematics, physics, and electrical engineering, rather than focusing heavily on what he called “the trendy technology du jour.”
LeCun on ‘Vibe Coding’ and AI-Assisted Programming
Addressing the growing trend of “vibe coding”—where developers rely heavily on AI tools to generate code—LeCun cautioned against abandoning core programming skills.
While he acknowledged that AI can significantly improve efficiency, he said it cannot replace a fundamental understanding of how computers and programs work. According to LeCun, developers still need to know how to write, debug, and reason about code, even in an AI-assisted future.
Conclusion
LeCun’s message is a reminder that while AI is transforming the tech industry, deep knowledge remains irreplaceable. As tools evolve, those with strong mathematical and scientific foundations are more likely to adapt, innovate, and remain relevant over decades—not just product cycless
Final Thoughts from TheTrendingPeople
In an era obsessed with speed and shortcuts, Yann LeCun’s advice cuts against the grain. His argument is clear: technologies will change, programming tools will evolve, but mathematical thinking and foundational understanding endure. For students navigating an AI-driven future, depth—not hype—may prove to be the most valuable skill of all.
