You know what the old software was. The task, taken out of the day, for a hundred million people at once, at no extra cost, and the old license, priced on the task, going down with it.
You know what the new software is. The role. The agent takes the bookkeeper's seat, the paralegal's stack of contracts and the pen tester's night shift, and a company recording its own employees' keystrokes is recording the roles it will automate next.
You know who builds it. Before AI, I was already building automation frameworks to do the same job in the test environment. All I have to do now is hook the large language model up to Playwright through MCP, and the same automation runs with an agentic brain, in production. The model is the brain and Playwright is the arm, and the harness, the evaluation and the ownership are the job. Every job that can be done in front of a computer can be done by an agent, so where we used to build software, now we build agents, and every agent needs what every piece of software ever needed: somebody who takes responsibility for whether it works. Software quality assurance becomes agent quality assurance. The software quality assurance engineer becomes the agent quality assurance engineer, and nobody will do this better than you. You already have the first half. The second half is a tool and a way of working, and both can be learned.
So when somebody asks you what a test automation engineer is for now, say it the way I say it. If robots are going to take over the world, I want to work for the robot factory. If agents are taking over the world, I want to work for the agent factory.
