Context Engineering 2.0: a 28-page PDF maps four eras of human-AI interaction
mdancho84 · x · 2026-11-14
A new 28-page PDF, "Context Engineering 2.0," declares "RIP Prompt Engineering" and argues machines fail not from lack of intelligence but from inability to reduce information entropy — they need contexts preprocessed for them. Key points:
- Four eras of human-AI interaction: Context 1.0 (translation) → 2.0 (instruction) → 3.0 (scenario) → 4.0 (world), with roles evolving from passive executor to initiative agent, reliable collaborator, and considerate master.
- Core law: more intelligence means lower human-AI interaction cost. The gap between carbon-based and silicon-based cognitive ability is the very motivation for context engineering.
- We're currently in Era 2.0 transitioning to 3.0, which changes memory design (layered architectures) and multi-agent collaboration (shared memory and subagents).
