Agents built on Unix primitives gain model-portable, file-based state¶
Insight: According to Marc Andreessen, combining language models with Unix primitives — shell, filesystem, plain-text files, cron — is what makes today's coding agents architecturally novel. Because state lives in human-readable files rather than model weights, agents become model-agnostic: the underlying LLM can be swapped without losing the agent's identity, history, or in-progress work.
Detail: Andreessen frames this as an extension of why text protocols (HTTP, HTML) outcompeted binary alternatives — readability scales learning. Treat this as an early framing claim from a single non-engineering source rather than a verified architectural pattern.
