# AI Evolution: Breakthroughs That Unlocked the Next Era

A source-first, breakthrough-centered map of AI history. This is not a citation ranking or a claim that one person single-handedly caused a field transition. Each card asks what was blocked, what changed, and what became possible.

## Start here

1. [ImageNet–AlexNet](breakthroughs/imagenet-alexnet.md): data, compute, architecture, and benchmark feedback converged to make deep visual learning undeniable.
2. [The Transformer](breakthroughs/transformer.md): attention-only sequence modeling traded recurrence for parallelizable computation.
3. [AlphaFold2](breakthroughs/alphafold.md): learned structure prediction became a scientific instrument at unprecedented scale.

## Learning paths

- **From deep learning to current foundation models:** ImageNet–AlexNet → The Transformer. Compare the role of benchmark/data scale with architectural parallelism.
- **From general methods to consequential applications:** The Transformer → AlphaFold2. Track how representation learning and engineering meet a domain-specific scientific bottleneck.
- **Operator's lens:** For each card, read “What was blocked,” “What changed,” “Practical leverage,” then “Limits.” Ask which constraint in a current project resembles the historical bottleneck; do not assume the old solution transfers unchanged.

## Evidence and interpretation

Each claim should be traceable to the references listed on its note. “Documented” claims summarize cited sources; “Interpretation” and “Practical leverage” are synthesis, not quotations or established historical consensus. Sources were retrieved and checked on 2026-10-05 America/New_York. Retrieval proves the cited page was reachable, not that every inference is beyond dispute. See [schema](SCHEMA.md) and [agent guide](AGENTS.md).
