Every significant milestone, model, framework, tool, protocol, and trend in artificial intelligence — from the McCulloch-Pitts neuron to agentic AI — in one comprehensive reference document.
This is a 12,000+ word, 15-part reference document covering the complete history and current landscape of AI and machine learning. Written for practitioners who want to understand not just what happened, but why it mattered and how each piece connects to the next.

Most AI timelines list events. This one explains them — why each milestone happened, what problem it solved, how it connects to what came before and after, and what it means for practitioners working in the field today.
Early periods (pre-2020): Concise 3–5 paragraph entries covering what mattered and why.
Recent developments (2023–2026): Deep coverage with multiple paragraphs per topic — including the full context of MCP, agentic AI frameworks, LLM evaluation, MLOps tooling, fine-tuning methods (LoRA, QLoRA, DPO, GRPO, ORPO), and the "vibe coding" / no-code AI phenomenon.
