Redefining Evolution: Functional Information and Cosmic Complexity

2025-04-14

Scientists propose a new theory of evolution: functional information. This theory suggests that selective processes drive the evolution of complex systems, not limited to biology but applicable to minerals, elements, and even the universe itself. This evolution isn't always gradual; sometimes it occurs in jumps, such as at key points in biological history. The concept of functional information offers a new perspective on understanding the origin of cosmic complexity and the direction of life's evolution, providing new avenues for research in astrobiology, oncology, and other fields.

Beyond Stochastic Parrots: The Circuits of Large Language Models

2025-04-13

Large language models (LLMs) have been dismissed by some as mere "stochastic parrots," simply memorizing and regurgitating statistical patterns from their training data. However, recent research reveals a more nuanced reality. Researchers have discovered complex internal "circuits"—self-learned algorithms that solve specific problem classes—within these models. These circuits enable generalization to unseen situations, such as generating rhyming couplets and even proactively planning the structure of these couplets. While limitations remain, these findings challenge the "stochastic parrot" narrative and raise deeper questions about the nature of model intelligence: can LLMs independently generate new circuits to solve entirely novel problems?

Unraveling Predator-Prey Cycles: The Lotka-Volterra Equations

2025-04-13

The Lotka-Volterra equations, also known as the Lotka-Volterra predator-prey model, are a pair of first-order nonlinear differential equations often used to describe the dynamics of biological systems where two species interact, one as a predator and the other as prey. The model assumes prey have unlimited food and reproduce exponentially unless preyed upon; the predation rate is proportional to the rate at which predators and prey meet. Predator population growth depends on the predation rate and is affected by natural death rate. The model's solutions are deterministic and continuous, meaning predator and prey generations continuously overlap. The Lotka-Volterra model predicts fluctuating predator and prey population numbers and reveals characteristics of population equilibrium: prey equilibrium density depends on predator parameters, while predator equilibrium density depends on prey parameters. The model has found applications in economics and marketing, describing dynamics in markets with multiple competitors, complementary platforms, and products.

The Paradox of Effort in AI Development

2025-04-11

Using the childhood analogy of damming a creek, the author explores the tension between striving for maximum effort and making wise choices in AI development. Initially, like a child, the author tried building dams with small rocks and leaves, only to discover a more efficient method with a shovel. This realization highlights how 'victory' can sometimes mean a shrinking of the game's space. Similarly, in AI, the author relentlessly pursued an investment banking job, only to find, upon success, that the game of 'making as much money as possible' was no longer available. He argues that against overwhelming forces (nature, the market), full effort can be counterproductive. Anthropic's recent report on educational applications, however, suggests a growing awareness of potential risks, akin to noticing the struggling clams on a beach.
