Agents write code.
They do not own it.
Building is easy now. Engineering is what survives.
An agent can produce a working feature in an afternoon. What it cannot do is carry the result: understand why it was built that way, notice when it starts to rot, and be the person who answers for it at 2am. That part still needs a human, and on a lot of small teams right now, nobody has that job.

None of that is an argument against agents. It is an argument for someone who owns what they produce. Next page: what that person's team looks like.
