As a spillover of the application of artificial intelligence (AI) across many fields, questions about the nature and forms of intelligence have acquired new urgency. In many ways, this has revived an old philosophical puzzle: what exactly does it mean to think, to know, or to understand? 

Long before these questions entered everyday conversation through technology, they had appeared in an unlikely place. They surfaced in the writings of the British author Douglas Adams, whose playful imagination often touched philosophical concerns that resonate differently today.

Today, March 11, marks the birth anniversary of Adams, best known for the classic The Hitchhiker’s Guide to the Galaxy. What began as a humorous radio series for the BBC in the late 1970s later became a bestselling novel and a cultural phenomenon. Yet beneath its absurd humour lay an idea that now appears remarkably relevant in the age of AI.

Adams, born in Cambridge in 1952, was not a scientist or a technologist. He was a writer who combined speculative imagination with philosophical humour. In his storytelling, he explored questions about knowledge, intelligence and the limits of human certainty. Those themes, which once appeared merely comic or whimsical, now feel strikingly contemporary in a world where AI systems increasingly shape everyday decisions.

The Hitchhiker’s Guide to the Galaxy (1979) begins with a deliberately absurd premise. Earth is demolished by alien bureaucrats to make way for an interstellar highway, and an ordinary Englishman named Arthur Dent survives only because he is rescued by a friend who turns out to be an alien researcher. Dent's accidental journey across the galaxy introduces readers to eccentric travellers, malfunctioning machines and cosmic institutions that behave with the same mixture of arrogance and confusion often seen in human bureaucracies.

Beneath the book’s comic appeal, however, lies a philosophical idea that now feels surprisingly relevant. In one famous episode, an advanced civilisation constructs a vast supercomputer called Deep Thought and asks it to calculate the ultimate answer to life, the universe and everything. After millions of years of calculation, the computer finally produces the answer: forty-two.

The philosophers who commissioned the machine react with disbelief. The answer seems meaningless. Deep Thought calmly explains the difficulty. The answer itself may be correct, but the beings who asked the question never clearly understood what the question actually was. The machine therefore performed its task exactly as instructed. The real problem was that the question had never been properly framed.

This comic episode reads today as more than a joke about machines. It raises a deeper question about intelligence itself. In some ways, writer and columnist Manu Joseph has also reflected on this aspect in a recent piece. Joseph argues that much of what humans describe as intelligent thinking often consists of recognising patterns and producing plausible responses rather than possessing complete understanding. Seen in this light, machines that generate convincing answers appear less mysterious than they first seem.

Adams wrote his story at a time when computers were still primitive tools used mainly for calculation. The insight behind his fictional computer therefore appears unexpectedly perceptive today. Modern AI systems generate text, analyse images, translate languages and assist with complex forms of decision-making. Large language models answer questions in fluent language and often produce responses that sound authoritative even when their reasoning is statistical rather than conceptual.

Machines can therefore produce answers quickly and convincingly. The quality of those answers still depends heavily on the questions that humans ask. AI can summarise information, detect patterns or suggest solutions. Determining which problems are worth solving remains a human responsibility.

Human intelligence itself does not always operate through careful reasoning. People drive vehicles, speak languages and make complicated judgments without necessarily understanding the underlying principles in detail. In that sense, AI reflects certain features of human cognition rather than representing a completely alien form of intelligence.

The character of Adams’ humour also deserves attention. His writing is often described as comedy or satire, yet it rarely seeks loud laughter. The humour works through recognition rather than spectacle. Absurd situations in his fictional universe resemble familiar patterns of human behaviour. Bureaucratic confusion, misplaced confidence and the search for simple answers to complicated problems appear in exaggerated but recognisable form.

This restrained style of satire gives Adams’ ideas a durability that extends beyond the comic setting. The fictional computer Deep Thought does not merely deliver a punchline. The episode reveals a tension about knowledge and authority. Humans build machines to generate answers, yet uncertainty persists about the questions that truly matter.

The same tension appears in contemporary discussions about AI. Governments, corporations and universities increasingly rely on algorithmic systems to assist with decision-making. AI tools analyse medical images, detect financial fraud, translate languages and evaluate large datasets. Their capabilities continue to expand rapidly.

The deeper challenge, however, remains intellectual rather than computational. A machine can process enormous quantities of information, but it cannot independently determine questions of wisdom, justice or social priority. Those decisions remain embedded in human institutions.

This issue is particularly relevant in countries such as India, where digital technologies are expanding rapidly across society. India has built one of the world’s most ambitious digital public infrastructures, linking identity systems, payment networks and public services through large technological platforms. AI is now being explored in areas such as agriculture, healthcare, education and language translation.

The potential benefits are considerable. AI systems may assist doctors in diagnosing diseases, help farmers anticipate crop patterns and expand educational access through language technologies. At the same time, these developments raise questions about data quality, institutional accountability and the broader goals that guide technological policy.

Adams’ fictional computer offers a useful metaphor for this moment. The machine in his story performs its task flawlessly within the instructions it receives. The real difficulty lies in defining those instructions wisely. Technological sophistication cannot substitute for clarity about the purposes it serves.

Douglas Adams himself was fascinated by emerging technologies. Friends and colleagues often recalled that he was among the early enthusiasts of personal computers and the internet during the 1980s and 1990s. He once remarked that technology invented after one’s birth tends to feel unfamiliar, while older technologies appear natural and inevitable. The observation captured how quickly societies adapt to new tools without fully examining their consequences.

Current debates about AI often swing between excitement and anxiety, sometimes overplaying both. Responses tend to split between those who see AI as a powerful engine of scientific discovery and economic growth and those who worry about misinformation, employment disruption and automated decision-making.

Revisiting Adams on his birth anniversary offers a calmer perspective on these debates. His fiction reminds readers that technological intelligence, however sophisticated, does not remove human judgment. Nearly half a century after The Hitchhiker’s Guide to the Galaxy first appeared, Adams’ cosmic canvas seems today to carry a quiet subtext that speaks directly to the present.
