“AI is like teenage sex—everyone talks about it, nobody really knows how to do it.” — Andrew Ng, AI guru

Andrew Ng, captures the sense of hype, confusion, and uncertainty that has often surrounded artificial intelligence (AI) in recent years. Delivered with humor, it reflects the atmosphere in which AI has become a buzzword: widely discussed in boardrooms, newsrooms, and tech circles, yet rarely understood in its real-world applications or complexities.

The backdrop to this quote is the rapid growth in public and corporate interest in AI. From the early days of AI research in the mid-20th century, the field has experienced cycles of intense excitement (“AI springs”) and subsequent setbacks (“AI winters”), often fueled by unrealistic expectations and misunderstanding of the technology’s actual capabilities. In the last decade, as machine learning and deep learning began to make headlines with breakthroughs in image recognition, natural language processing, and game-playing, many organizations felt pressure to claim they were leveraging AI—regardless of whether they truly understood how to implement it or what it could achieve.

Ng’s remark wittily punctures the inflated discourse by suggesting that, like teenage sex, the reality of AI is far less straightforward than the bravado implies. It serves as both a caution and an invitation: to move beyond surface-level conversations and focus instead on genuine understanding and effective implementation.

About Andrew Ng

Andrew Ng is one of the most influential figures in artificial intelligence and machine learning. He is known for his clear-eyed optimism and his ability to communicate complex technical ideas in accessible language. Ng co-founded Google Brain, led Baidu’s AI Group, and launched the pioneering online machine learning course on Coursera, which has introduced AI to millions worldwide.

Ng frequently emphasizes AI’s transformative potential, famously stating that “AI is the new electricity”—suggesting that, much like electricity revolutionized industries in the past, AI will fundamentally change every sector in the coming decades. Beyond technical achievement, he advocates for practical and responsible adoption of AI, striving to bridge the gap between hype and meaningful progress.

His humorous comparison of AI discourse to teenage sex has become a memorable and oft-cited line at technology conferences and in articles. It encapsulates not only the social dynamics at play in emerging technological fields, but also Ng’s approachable style and his drive to demystify artificial intelligence for a broader audience
