A trireme was the warship that made Athens a power in the Mediterranean — not for its size, but for its structure. Three banks of oars, a hundred and seventy rowers, every bench pulling in time with every other. Take enough rowers out of one bank and the ship doesn’t row slower. It stops being a trireme.

There’s a counterargument to this whole series that I keep hearing, and it’s a good one. One person plus a good agent can do the work of a small team. The agent implements, you review, you ship. So why the other five people?

For a lot of work, that’s just true. A solo developer with a sharp agent will out-ship a small team that hasn’t figured out how to use one. I’m not going to pretend otherwise.

But run that way long enough and you hit a specific failure — and it isn’t running out of hours. It’s that the only thing checking your work is a thing built to agree with you. I went at this from the agent’s side in the ever-agreeing genie — the model that grants the wish exactly as worded and never asks whether it was the right one. The team’s side is the same problem wearing different clothes. The agent validates against your prompt, your prompt is your current understanding, and your current understanding has holes you can’t see, because that’s what a blind spot is. Working solo, nothing in the loop ever touches them.
