Investment: The Age-Friendly Profession

 In a world where most careers fade with age, investing — particularly value-oriented investing — stands out as an art that matures with time. Charlie Munger once remarked, “Warren has improved since he passed the retirement age of man.” In few fields can one say that performance continues to climb even after most people have long left the stage. Yet for Warren Buffett, and many like him, their best decades often arrive when their hair turns gray and their pace slows.

Why is that?

1. A Career Where Stillness Wins

In the realm of investing, one is rewarded not for motion, but for judgment. It is a rare profession where doing nothing is often the best decision — where patience, not energy, is power. Unlike corporate management, which demands ceaseless activity, meetings, and politics, the investor’s task is one of mental clarity — deciding when to act, not how often to act.

Managers rise and fall within organizational mazes. Their success often depends on navigating bureaucracy, tempering egos, and sustaining constant motion — a battle against entropy and human nature. Investors, on the other hand, are freed from these micro dramas. Their battlefield lies not in offices, but in the quiet chambers of their own minds.

2. The Long Apprenticeship in Human Nature

Investing is not a business of numbers; it is a business of understanding people. Every price chart, every balance sheet, every macro signal — beneath them all are human decisions, driven by fear, greed, hope, and bias. The economy, after all, is just a mirror of collective psychology.

To excel in investing is to develop a profound understanding of human nature — to recognize not only the follies of others, but one’s own. And such understanding does not arrive quickly. It must be earned. Time and suffering are the tuition.

True wisdom emerges not from books or spreadsheets, but from scars — from losses survived, bubbles endured, and mistakes faced with humility. We grow when we suffer, or when we have the patience to learn deeply from others’ suffering. That is why, in this field, age is not a handicap — it is an edge.

3. Compounding Beyond Money

Investors enjoy a privilege few professions offer: the ability to compound across multiple dimensions. Good decisions compound into wealth; good reflections compound into wisdom. The very practice of investing — requiring calm, curiosity, open-mindedness, and detachment — nurtures a healthier, more equanimous state of mind.

While a corporate executive may face diminishing returns on energy and stamina, an investor’s returns are driven by perspective — something only time can bestow. Each passing year adds a layer of insight, humility, and mental resilience. Thus, it’s not surprising that many great investors perform at their peak in their seventies, eighties, or even nineties.

4. Until the Robots Arrive

Perhaps one day, when humanoids roam trading floors and AI systems allocate capital with perfect rationality, the age advantage may disappear. In a world governed by machine precision, emotional mastery might no longer matter. But until that science fiction future arrives, investing remains a deeply human endeavor — shaped by psychology, temperament, and time.

5. The Wide and Long Snow Track

Investing is like skiing on a wide, long snow track — the slope is gentle, but endless. The longer you stay on it, the more momentum you gain. It is not a sprint, but a lifelong glide.

In this sense, value investing is not just a way to become richer, but a path to becoming wiser, calmer, and perhaps even happier. It is a rare profession where aging does not mean decline, but deepening — where one’s greatest asset is not youth, but the years lived and lessons learned.

Silicon vs. Carbon: A Tale of Two Intelligences

Silicon Intelligence vs. Carbon Intelligence: A Tale of Two Energies “Artificial Intelligence” is a misnomer, if you ask me. I’d rather call it Silicon Intelligence . After all, it runs on silicon chips (at least for now) and is powered by electricity. By contrast, human intelligence is carbon-based—built from DNA and fueled by bioelectricity. Ultimately, all that energy—whether from a GPU cluster or a human brain—traces back to the sun : The past sun powers us via coal, oil, and gas. The present sun drives wind turbines, solar panels, and photosynthesis (plant food included). Preset Parameters and the Art of Learning When a baby is born, much of their foundational “mental model” is wired by genetics. As Charlie Munger famously quipped, “They’re like machines with 80% of the parameters preset.” But humans are also learning machines . We don’t recompile—we reflect. And if we’re lucky, we wake up “a little less stupid” each day. Large language models improve similarly—via fine-...

The Ghost in the Machine: How Human Cognitive Biases Shape the Alignment, Context, and Tuning of Large Language Models

 The entire discipline of guiding LLM outputs can be reframed through the lens of "choice architecture," a concept from behavioral economics introduced by Richard Thaler and Cass Sunstein. Choice architecture is the design of the environment in which people make decisions; it posits that the way choices are presented—the "architecture"—inevitably influences the outcome, whether intentionally or not. A choice architect, therefore, is anyone who organizes the context in which people make decisions. In the realm of LLMs, prompt engineers and the designers of Retrieval-Augmented Generation (RAG) systems are the new choice architects. They are not merely instructing a machine; they are designing a decision-making environment for an artificial intelligence. This section argues that this process is profoundly shaped by the same heuristics and biases that affect human decision-making, turning context engineering into a practice of creating flawed choice architectures.

For Whom the Bot Toils: Navigating the Great Inequality of the Gen AI Era

 We stand at the precipice of a revolution, one powered not by steam or silicon, but by syntax and servers. The rise of Generative AI has been heralded as the dawn of democratized intelligence, a future where every individual has a brilliant co-pilot in their pocket. Yet, as we watch this new world take shape, a rather inconvenient and increasingly stark reality is emerging: the algorithm giveth, and the algorithm taketh away—on a scale that would make John D. Rockefeller blush. The economic landscape is beginning to look less like a level playing field and more like a cartoon where one character has a rocket ship and everyone else has a pogo stick. On one hand, we see super-intelligence labs at companies like Meta offering compensation packages to top AI researchers that resemble the GDP of a small island nation. These are the new high priests of progress, crafting the digital deities that will define our future. In parallel, tech titans like Microsoft and Nvidia are soaring towar...
