Our Commentary ​

This is a classic Simon Willison deep dive. We appreciate his clarity on what feels like an intentionally confusing product. The idea of a persistent filesystem and headless Chrome within ChatGPT Work is genuinely fascinating. It hints at a future where AI agents have more autonomy and memory. I'm still trying to wrap my head around the implications for developer workflows.
