The Architecture of AGI: An Interactive Mind Map Explorer

Traditional AI overviews often isolate machine learning from its broader philosophical and physical constraints. But understanding the path to true Artificial General Intelligence demands a far more sophisticated, multi-disciplinary framework.

The AGI State-of-the-Art Mind Map Explorer expands classical AI taxonomies into an interactive, multi-level systems-thinking model capable of tracking cognitive foundations, neuro-symbolic hybrid architectures, alignment safety theory, world models, and underlying hardware boundaries.

This interactive visual taxonomy explores:

• Cognitive Foundations, Abstract Reasoning, and Human Intelligence Analogies
• Neuro-Symbolic Hybrid Architectures, Connectionist Systems, and World Models (JEPA)
• Silicon Physical Limits, Neuromorphic Computing, and Substrate Alternatives
• General Learning Mechanisms, Self-Supervision, and Continual Adaptation Horizons
• Dynamic Memory Architectures, Test-Time Compute Scaling, and Causal Search Planes
• Holistic Indicators (ARC, GAIA), Alignment Theory, Technical Guardrails, and Compute Governance

Technical Note on Notation

In classical geometry, 53/2° is the traditional shorthand for the angle whose tangent is exactly 1/2. While its decimal approximation is ≈ 26.565°, the synthetic beauty of Problem 1613 relies on the exact 1:2 ratio. For the purpose of this proof, 53/2° is defined as arctan(1/2), ensuring absolute mathematical rigor in the 2:1 relationship.
