Computer use and browser agents

Plain English. Agents that operate software the way a person does — looking at the screen, clicking, typing, driving a browser — rather than through purpose-built APIs. It is the bridge between chatbots and labour substitution, because most work still lives in interfaces built for humans.

Why it moves money. Whatever software an agent can operate, it can staff. Platform owners are moving to own the surface: Apple is building toward an agent that operates the device on your behalf, and Safari now exposes the browser to agents natively. The same capability is a security surface — an agent that can use a computer can misuse one — so reliability and containment, not capability, set the adoption rate.

What to watch. Task-completion rates on real GUI work (still the weakest agent benchmark category), and the first enterprise-scale incidents traced to a browser agent.

From the signals. Apple moves toward an agent that operates the device on your behalf. Safari ships an MCP server: the browser becomes an agent surface.
