AI's Next Big Fight: Who Controls Your Agent?

OpenAI, Google, and Workday all sell AI agents. But they disagree on one key question: where those agents should live. An AI agent is software that acts on its own to complete tasks for a user. Each company wants its agents to operate inside its own platform. That means buyers face a lasting decision: which company's system to build on. The choice is hard to undo. Once a business commits to one platform, switching later is costly. For buyers, the real question is not which agent is best today, but whose ecosystem they trust for the long term.
