$Agentic Development Fallacies

1. If the prompt is clear, the result will be correct.
2. More autonomy means more productivity.
3. If the code works, the agent understood the problem.
4. Plausible code is performant code.
5. Agents remove the need to understand the codebase.
6. A successful demo means the workflow scales.
7. More agents means more intelligence.
8. Humans are the fallback.

Cheaper implementation, costlier everything else

The misconception underneath all eight is that agentic development is programming, faster. It is closer to a change in which parts are expensive.

When implementation gets cheap, everything implementation used to pay for gets relatively more expensive: specification, architecture, evaluation, observability, performance work, verification, judgement.

The framing here is borrowed from the fallacies of distributed computing.
