As One Useful Thing's guide highlights, the shift from chatbots to agentic systems represents a fundamental change in how AI is used, moving from conversation to delegation. However, the analysis underplays the profound trade-off this entails: convenience is being exchanged for autonomy and transparency. By funneling users toward integrated platforms like ChatGPT Work and Claude Cowork, the industry is effectively making the agent's 'computer' a proprietary black box.
This centralizes control over the tools, data flows, and ultimately the value chain of AI-assisted work. The future battleground may not be whose model is smarter, but who controls the operating environment where that intelligence acts.
