Lol, allow us to introduce you to: Middle Management. Among other things, they have Budgets. If they don't use their full budget this year, it may be reduced next year. Spend!!!
OTOH, if everyone is becoming a team manager, then everyone will be payed a manager's salary! right? Right?...
On the serious side, though, the article proposes a world in which skilled employees are reviewing the un-skilled output of "Agents". It leaves out completely the process by which one _becomes_ skilled, and able to perform this review. No, no no, you can't *do* the work to learn it. Your job is to *know* the work and _fix_ the Actually Garbage output. If you don't know it already, we don't need to hire you. -> In about ten years, there is going to be another drop in certain skillsets (like COBOL - of the AI age) which will suddenly become high-paying (anything that was "agent-ized", and in the mean time everyone is going to go to smaller start-ups (now) and learn and do different things, as always happens.
You should be looking to start-ups and smaller companies. That's where your skills will develop, and where you'll find jobs, and teams and people who need you and appreciate your presence. (They're people though, so certainly don't approach as though you're their savior - everything is ok, now that they have You.)
The biggest risk of Agentization is: it can't do the job, perfectly. You're stuck with the agents, they're part of the process. You're stuck with the skilled labor: you need people to check it and correct it. On top of that, you're *also* stuck training and developing all the people you had to train and develop before - so that you can ensure the agentic output continues to be correct and get fixed. Agentization is double-cost. Ouch.
