Task specification

 Task specification - " writing concrete chunks of code/comments myself and in the right part of the code is a high bandwidth way of communicating "task specification" to the LLM, i.e. it's primarily about task specification bits - it takes too many bits and too much latency to communicate what I want in text, and it's faster to just demonstrate it in the code and in the right place.

anything that can be evolved can be efficiently modeled. - Lex Fridman

 That’s a deep and provocative insight — and it aligns remarkably well with modern trends in AI, biology, and even physics. Let’s explore what you mean and why it matters.


🧠 Statement: “Anything that can be evolved can be efficiently modeled.”

Let’s unpack this.

1. Evolved Systems Are Compressible

  • Evolution operates over millions of trials, but through slow, iterative improvement, not random chaos.

  • This means evolved systems (e.g. proteins, languages, behaviors) exhibit regularities, constraints, and patterns.

  • These patterns can often be learned — that’s what machine learning models like AlphaFold or LLMs exploit.

If nature can "find" a solution via mutation and selection, then a model can often learn to approximate or simulate that search process — much faster.


2. Examples Where This Principle Holds

DomainEvolutionary Origin?Efficiently Modeled?
Protein foldingYes (natural selection)Yes (AlphaFold)
LanguageYes (cultural evolution)Yes (GPT, LLMs)
Behavior & strategyYes (biological & cultural)Yes (AlphaGo, RL agents)
Vision / perceptionYes (biological)Yes (ConvNets, ViTs)
Gene regulationYesPartially (deep genomics)

🔄 Why Evolution Implies Modelability

Here’s the logic:

Evolution is a search algorithm.
If it can find good solutions in a massive space (over time), then those solutions must exist in a compressed, learnable form.

So if you give a learning system:

  • Enough examples (data from evolution),

  • The right inductive bias (architecture),

  • And compute (training time),

…it can often shortcut the evolutionary process by learning the underlying patterns.


🧬 In Proteins:

  • Nature explored folds through mutation + selection.

  • AlphaFold learned the statistical patterns in those folds.

  • Result: it predicts in seconds what nature took billions of years to refine.


🧠 Implications: If It’s Evolved, It’s Learnable

This idea hints at something deeper:

  • Evolution is slow, modeling is fast.

  • Evolution finds instances, modeling builds generalizations.

  • If a phenomenon is too chaotic or non-evolved (e.g. turbulence, quantum randomness), we might not be able to model it efficiently.


🚫 Counterexamples? (Limits of the Principle)

Some systems may not be evolved in the same way:

  • Chaotic systems (weather, turbulence)

  • Truly random or adversarial systems

  • Non-biological emergent systems (e.g. stock markets)

Even here, though, parts of the system might be modeled locally, even if not globally.


🧩 Final Thought

“If evolution can find it, a model can learn it.”

This principle underlies much of modern AI — from LLMs to AlphaFold to reinforcement learning agents. It’s not just poetic; it’s a working assumption of deep learning's success.

Would you like to explore how this applies to cultural evolution, or maybe how it informs artificial life or AGI discussions?

You said:

ChatGPT said:

Great — let’s take the idea, “Anything that can be evolved can be efficiently modeled,” and explore how it extends into cultural evolution, artificial life, and even AGI (Artificial General Intelligence).


🧠 1. Cultural Evolution and Modelability

Just like biological evolution shapes genes and proteins, culture evolves through:

  • Transmission (learning, imitation)

  • Variation (in ideas, tools, behaviors)

  • Selection (via utility, popularity, survival)

This means language, technology, art, norms, and even religions are shaped by long evolutionary processes — and they exhibit the same compressible patterns.

✅ Evidence: Language Models

  • Language is culturally evolved and shaped by usage.

  • LLMs (like GPT) are efficient statistical models of evolved language.

  • These models learn cultural priors: metaphors, logic, storytelling, ethics.

“If language evolved, it can be modeled. If it’s modeled, it can be reasoned about.”

So, tools like LLMs are not just text predictors — they’re cultural mirrors that reflect accumulated human intelligence.


🧬 2. Artificial Life (A-Life)

A-Life explores digital organisms that evolve in silico:

  • Mutation + selection → novel code, behavior, structures

  • Simulations like Tierra, Avida, or even Neuroevolution

✨ Relevance:

  • If digital evolution creates complex forms, then models can learn to predict or control them.

  • Neural networks can mimic evolved behaviors, and sometimes even outperform them in optimization.

In a way, A-Life systems provide training data for models of evolution itself.


🧠 3. AGI: The Ultimate Model of Evolutionary Intelligence?

AGI aims to replicate the general-purpose intelligence shaped by biological and cultural evolution.

Here’s where your principle becomes profound:

If human-level intelligence evolved, and if the pressure that shaped it can be simulated or learned from, then AGI may be achieved by modeling that evolutionary process.

✅ What we already do:

  • Reinforcement learning = model of reward-seeking behavior.

  • LLMs = model of linguistic and conceptual evolution.

  • Meta-learning = model of learning-to-learn (like evolution’s shortcut).

🔁 AGI Hypothesis:

A scalable, general-purpose learning system trained on the full stack of evolutionarily-shaped data (sensory, language, motor, memory, goals) could approximate or even exceed evolved biological intelligence.


🧩 Synthesis: Evolution as Computation, Models as Compressors

Biological structureProtein foldingAlphaFold
Behavior & planningAnimal intelligenceRL agents (AlphaGo)
Language & cultureCultural transmissionLLMs (GPT, Claude, etc.)
Tool useHuman innovationFoundation models
Learning abilityEvolution of brainsMeta-learning / AGI

🚀 Final Reflection

Evolution is nature's brute-force algorithm.
Machine learning is our compression of its results.

The closer we can get to modeling what evolution has already discovered — whether in biology, language, or cognition — the more powerful and general our artificial systems will become.


Would you like to go even deeper — perhaps explore:

  • The idea of evolution as computation?

  • Or whether LLMs themselves are evolving through training loops and feedback?

Demis Hassabis

"with the Alpha X projects, so I’m thinking AlphaGo, of course, AlphaFold, what they really are is we are building models of very combinatorially, high dimensional spaces that if you try to brute force a solution, find the best move and go, or find the exact shape of a protein, and if you enumerated all the possibilities, there wouldn’t be enough time in the time of the universe."

You're absolutely right — both AlphaGo and AlphaFold tackled combinatorially explosive problems where brute-force enumeration is impossible. What made the Alpha projects successful is not just computational power, but smart modeling of massive search spaces. Here's how they approached it:


🧠 The Core Idea: Model the Space, Don't Enumerate It

Both problems involve astronomical possibilities:

ProblemSize of Search Space
Go>10¹⁷⁰ possible board configurations
Protein folding~10³⁰⁰ possible conformations for a small protein

Searching these spaces directly is like trying to find a needle in a universe of haystacks. So they didn't search directly — they learned patterns that make intelligent guesses far more efficient than brute force.


🔍 How AlphaGo Did It (Game Playing)

AlphaGo used:

  1. Policy network – predicts the most promising next moves (reducing branching factor).

  2. Value network – estimates who is winning from any given board state.

  3. Monte Carlo Tree Search (MCTS) – selectively explores move sequences using the above networks to prioritize paths.

Key Insight: Don’t simulate every move — simulate only the most relevant ones using learned heuristics.


🧬 How AlphaFold Did It (Protein Folding)

AlphaFold (especially AlphaFold 2) used:

  1. Large-scale training on protein databases – learned statistical patterns in protein sequences and structures.

  2. Evoformer – a deep neural architecture that infers pairwise relationships between amino acids.

  3. Structure module – predicts 3D structure from inferred relationships.

Key Insight: It’s not necessary to simulate every quantum force or physical interaction — statistical modeling of evolutionary patterns is enough to approximate structure.


🎯 Common Themes: How They Conquered the Impossible

FeatureAlphaGoAlphaFold
Problem TypePlanning / OptimizationStructural Prediction
StrategyGuided simulation (MCTS + NN)Learned statistical approximation
Brute-force FeasibilityImpossibleImpossible
Key InnovationDeep learning + Tree searchTransformer-based structure prediction
Use of Domain KnowledgeYes (rules of Go, board symmetry)Yes (biology, multiple sequence alignment)

🧠 Deep Learning as a Shortcut Through Combinatorics

Rather than "solve" the entire space, they learned from data how to:

  • Recognize patterns that compress the space.

  • Prioritize plausible solutions (moves or folds).

  • Generalize from past data without needing full enumeration.

This is exactly why brute force is out, and learning is in — deep models are function approximators that give you good answers fast.


Would you like a deeper dive into AlphaFold 2’s architecture, or a visual analogy of how these spaces are compressed through learning?

You said:
sure
ChatGPT said:

Great! Let's break this down with two things:

  1. A visual analogy to understand how deep learning compresses huge spaces.

  2. A simplified architecture breakdown of AlphaFold 2, since it's a pinnacle of this idea.


🧠 1. Visual Analogy: How Deep Models Shortcut Massive Search Spaces

Imagine you're dropped into a dark mountain range the size of a planet. You're told to find the highest peak — but you can't see more than a few feet around you, and there's no map.

👎 Brute Force:

  • You try every path up every hill.

  • You’d die of old age before covering 0.000000001% of the area.

👍 Deep Learning Strategy (like AlphaGo or AlphaFold):

  • Before you even start, you’re trained on thousands of aerial photos of mountain ranges.

  • You learn to spot subtle signs of elevation changes.

  • When dropped into a new mountain range, you instantly guess the best few paths to try first — and you’re right 95% of the time.

Deep learning doesn’t "solve" the space — it learns a compressed representation of it, guided by experience.

This is how AlphaFold can predict a protein’s shape without evaluating all 10³⁰⁰ possibilities — it’s been "shown enough mountain ranges" (i.e., protein families and structures) to generalize well.


🧬 2. Simplified View of AlphaFold 2 Architecture

AlphaFold 2 is like a three-step system:

🧩 Step 1: Multiple Sequence Alignment (MSA)

  • Aligns your input protein sequence with related sequences from evolution (across species).

  • This gives clues about which amino acids evolve together, implying they might be close in 3D space.

Imagine tracing the ancestry of words across languages to infer grammar rules — that’s what MSA is doing with proteins.


🔁 Step 2: Evoformer

  • A Transformer-based neural network (like what powers GPT, but specialized).

  • It passes information back and forth between:

    • MSA features

    • Pairwise residue relationships (a 2D map of how likely two amino acids are to be near each other)

  • Think of this as massive relational reasoning: figuring out if A is near B, and B is near C, then what’s A’s relation to C?

It’s like a very smart Sudoku solver — piecing together spatial relationships between parts.


🧱 Step 3: Structure Module

  • Takes that 2D map and predicts the 3D atomic coordinates of the protein.

  • Uses a differentiable 3D geometry model — it knows how to build shapes from angles and distances.

Like going from a 2D floor plan to a full 3D house model.


🧠 What Makes AlphaFold 2 So Powerful?

  • It models structure and sequence jointly, not separately.

  • It iteratively refines predictions — feeding output structure back into the model to improve it.

  • Trained on a massive protein structure database (PDB) + evolutionary data.


TL;DR – Alpha Projects’ Superpower:

They didn’t brute-force the universe. They learned to see the shortcuts.

  • AlphaGo: Learns which moves matter in a vast game space.

  • AlphaFold: Learns which patterns in sequences matter for folding.
