Why More Cat Photos Won’t Make AI Debug Better

 

From Cats to Code: The Old AI Playbook

Before 2015, AI progress was simple: more task-specific data → better task performance.
If you wanted a model to spot cats, you just fed it millions of cat photos. The model got better because its entire world was defined by cats — nothing else mattered.

LLMs Don’t Play by Those Rules

Large language models (LLMs) flip this script. Say you want to boost an LLM’s debugging ability. Your first instinct might be: “Just give it endless debugging logs.” But unlike cat classifiers, LLMs don’t learn skills by marinating in one type of data. Debugging isn’t only about debugging cases — it’s about understanding programming languages, human intent, problem-solving strategies, and even natural-language explanations.

The Theory: Breadth Beats Narrowness

Here’s why:

  1. Old Models = Narrow Lens
    Classic models captured patterns within a tight distribution. More data from the same distribution (cats, voices, digits) always helped.

  2. LLMs = Broad World Lens
    LLMs are trained to model the structure of all language and symbolic expression. Their power comes from learning the underlying “grammar of thought,” not just examples of one task.

  3. Emergent Skills Need Diversity
    Capabilities like debugging, reasoning, or translation emerge only when the training data is wide enough to reflect diverse human expression. Feed an LLM only debugging logs, and it risks becoming narrow and brittle.

Pre-2015 AI thrived on piling up task-specific data, while LLMs need diversity first, specialization second. Fine-tuning (like reinforcement learning with debugging feedback) can sharpen performance, but only after the model has built a broad cognitive foundation.

The New Rule of the Game

Improving LLMs isn’t about “more of the same.” It’s about exposing them to richer, more varied perspectives — coding languages, human reasoning styles, cultural contexts. Debugging, medicine, or law are not isolated buckets of knowledge. They’re applications of a general reasoning engine that only breadth can build.

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...
