The Savanna Brain in a Silicon World: Why We Overreact to Life’s Fluctuations

 We’ve all been there. When life is quiet and "peaceful," we find ourselves restless, craving a new challenge or more "excitement." Yet, the moment a family member falls ill or a crisis hits, that perspective shifts instantly: Peace is the only blessing that matters.

Why is our internal compass so volatile? I’ve been reflecting on why our emotions fluctuate so wildly in the short term, and it usually comes down to one thing: We are operating on ancient software in a modern environment.

The Probability Paradox

Our "System 1" intuition—the fast, emotional brain—wasn’t built for statistical accuracy. It was built for survival. This leads to two major cognitive traps:

 * Survival Bias: We focus only on the visible samples—the "winners" or the immediate crises—ignoring the vast "base rate" of reality.

 * Asymmetric Risk: We feel the sting of a potential loss far more than the joy of an equivalent gain. On the prehistoric savanna, this made sense. "Not dying" was infinitely more important than "eating slightly better." To our ancestors, avoiding a single fatal mistake was the only way to stay in the game of evolution.

The Modern Mismatch

In today’s world, these instincts often misfire. When we suffer a setback, our brain screams at us to take "bigger risks" to recoup the loss—overestimating the importance of getting back to zero. Conversely, when things are going well, we become irrationally risk-averse unless driven by a fear of missing out (FOMO).

We also tend to practice "mental accounting"—separating our losses and gains into different emotional buckets. We give negative numbers a disproportionate weight, letting a single bad day overshadow a year of steady progress.

Finding Equilibrium

How do we balance the "caveman" within?

 * Look at the Base Rate: Whenever you feel an emotional spike, zoom out. What is the actual probability of this event? Don’t let "availability bias" (what’s currently in front of you) dictate your peace of mind.

 * Merge Your Accounts: Treat your life like a single ledger. Gains and losses are just numbers in the same account. Don't give a "minus" more power than a "plus."

 * Understand Your Instincts: Recognize that your anxiety is often just a legacy gene trying to protect you from a lion that no longer exists.

Modern society is a mere blink in the timeline of human history. Our genes haven't caught up to our spreadsheets yet. By understanding our biological "shortcomings," we can stop being victims of our fluctuations and start finding a more grounded, philosophical path forward.

Because in the end, the goal isn't just to win—it's to stay in the game.

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-...

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...

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.
