## Summary

A Hacker News essay argues that Frederick P. Brooks Jr.'s 1975 principle, "Adding manpower to a late software project makes it later," remains relevant in the era of AI. The author suggests that while AI agents eliminate traditional human bottlenecks like onboarding and meetings, they do not eliminate the fundamental constraints of sequential work. The "Baby Problem" persists: multiple agents cannot accelerate tasks that must happen in a specific order.

The piece contends that management overhead has shifted rather than disappeared. Instead of coordinating people, developers must now orchestrate agents, define completion criteria, and review outputs for hallucinations. Without clear requirements, multiple agents working on the same codebase can create conflicts and rewrite each other's work. The author proposes a modernized version of Brooks's Law: adding agents to a project with unclear requirements gets you the wrong answer faster.

## Key points

- Brooks's Law from 1975 suggests adding manpower to late projects delays them further.
- AI agents do not remove sequential task bottlenecks or the need for human oversight.
- Unclear requirements with multiple agents can lead to conflicting code and faster errors.

## Why it matters

This perspective tempers expectations for AI-driven productivity gains, reminding teams that clear requirements and human orchestration remain critical to avoid compounding errors in agent-based workflows.
