Why teams?
AI increases leverage. It does not remove the need for teams.
I often say teams are the lowest unit of ownership. Someone asked what I mean.
There’s always a human. Not because AI is dumb. Pattern-matching without verification is confident error, and humans overtrust themselves the same way. Leverage without challenge compounds it faster.
Ownership is accountability, responsibility, and autonomy: the team answers the questions, makes the calls, does the work, and controls the path to the goal.
Why not one human and a circus of agents? Or only the circus? Verification doesn’t scale on one person. More output. Nothing checking it. AIs are sycophantic; they add agreement, not friction. The 100x operator becomes the fastest source of unexamined decisions.
There is no conservation of energy here. Teams spread load. A lone operator with a circus of agents concentrates it. Once they’re out, the whole circus closes for the night.
You need texture. Everything smooth removes the thing that would have caught you. The better the agents, the smoother the surface, the worse the wipeout. The argument gets stronger as AI improves.
A colleague showed me Claude calling something a one-liner. It was fifteen lines of curl, jq and aws-cli.
Texture comes from people who all own the whole space, not a slice each. Everyone has standing to challenge decisions.
Two things govern this: how teams form, and how large they become. Teams need enough shared taste to move quickly, and enough deliberate difference to challenge each other when it matters. Too little friction and things slide through uncaught. Too much and the space becomes drag.
The two-pizza rule was always a proxy for this: how many full owners can share a space before overlap becomes drag. In the AI age the number shrinks. Never to one.
Effective isn’t fast. Fast looks productive. Effective gets the outcome with someone there to challenge you.
Reward teams, not individuals. Give teams ownership of their space. Curate them deliberately. Enough alignment to move quickly. Enough difference to create challenge. Never so small that all the load collapses onto one person. Better teams make better decisions.
