The article claims Work adds cloud execution with internet-capable code, a headless Chrome browser, persistent shared filesystem access across sessions, and capabilities like publishing ChatGPT Sites and running sub-agent sessions.

As a result, the piece shifts focus from endless RSI to faster, segmented progress across open models and more specialized AI hardware rather than expecting infinite acceleration in AI capabilities.
