The arrival of artificial intelligence (AI) raises the question of what role remains for humans. What is it that only humans can do, that makes it impossible for AI to replace us?
The answer is hopeful. To begin with, the human brain is a marvel in itself. It weighs only about 1.4 kilograms and operates on a mere 20 watts of power—enough energy to dimly light a refrigerator bulb. Yet training some of the world's most advanced AI systems requires data centers that consume hundreds of millions of watts of electricity, the level used by an entire city. These facilities are packed across vast sites with servers, massive cooling systems and long stretches of cabling. The human brain, by contrast, weighs 1.4 kilograms, uses less energy than a laptop charger and sits quietly inside the skull. And yet it still accomplishes things machines cannot solve.
Computer scientist Yann LeCun has pointed out that human intelligence is not mere computation. It is experience built from social understanding and emotional cognition accumulated through millions of years of evolution. So now we must stop regarding humans as inferior computers. We reduce intelligence to a narrow range of analytical reasoning ability that machines can optimize. But human consciousness is far richer and more mysterious than that. As AI's capabilities advance, we will paradoxically come to reconsider how precious uniquely human value is.
Novels, paintings and videos created by AI already flood the internet. Some are technically impressive. But most people pay little attention to them. That is because in art, the human behind the work matters more than the final product. We empathize with art precisely because it comes from another human being. When we read novels by Charles Dickens, Toni Morrison or Gabriel García Márquez, we are not simply appreciating elegantly arranged words. We enter their consciousness. We become interested in language that captures another human's suffering, imagination, doubt and hope. These writings are moving because, in a sense, they are imperfect. For decades, our society has encouraged us to think of humans as analyzing machines. But AI may perhaps make us rethink that entire framework. For if machines are vastly superior to humans at analysis, calculation and memorization, then what is uniquely human emerges all the more vividly.
The real danger of the AI era does not begin with machines becoming too human, but with humans trying to become like machines. We are already witnessing this. People increasingly treat every dimension of life—sleep, productivity, networking, branding, performance—through the lens of "optimization." Students feel pressure to construct perfectly managed résumés of themselves. Workers fear being compared to algorithms that never tire and never sleep. But human flourishing is not about optimization. A meaningful life is often messy, nonlinear, contradictory, emotional and inefficient. And the people who have made our lives most profound are not the most optimized but the most "human." Human greatness comes from fierce effort.
Someday a machine may compose a technically perfect symphony. But a machine will never know the anguish of Beethoven, who composed the Ninth Symphony, the greatest music in history. The Ninth Symphony moves us not as a mere arrangement of notes. It is the sorrow, perseverance and triumph of a composer who, having lost his hearing, sought to create transcendent music he could never hear. This is precisely why human intelligence matters. It is not because it is faster or more efficient than AI, but because it is rooted in the experience of life. Machines can help us solve problems. But it is still human intelligence that decides what is worth protecting and what is worth sacrificing for.
AI may transform not only medicine, science and education, but every profession that exists today. Yet even amid this enormous upheaval, people will crave what only humans can provide. And they will still want to be important to one another. The heart of human life lies in relationships. We seek recognition, dignity, affection and love from other humans. These are things we simply cannot obtain from a high-performing computer or AI. Rather than competing with AI on AI's terms, we must become more fully human through AI.
