Why The Best Engineers Say Coding Is Solved

TL;DR

• 1

  Both guests say they no longer write code by hand: Jeroen Gordijn and Jeroen Dee claim coding became unnecessary around Claude Opus 4/4.5 in late November 2024, and say their work has moved up a level from syntax to architecture, integrations, and system design.

• 2

  Human code review is becoming the bottleneck: As agents generate more pull requests, teams are drowning in large diffs, so they argue review should increasingly be automated and focused on higher risk changes rather than making humans read every line.

• 3

  Spec-driven development is their answer to agent chaos: Instead of "throwing a dart at the board," they use tools like OpenSpec to produce proposals, design docs, and human-readable behavior specs so models can generate code that actually fits the codebase.

• 4

  The end state is a 'dark factory' for software: Their ideal workflow is specs in, implementation and self-review loops run automatically, proofs like screenshots or API request-response traces get attached, and humans mainly validate specs and outcomes.

• 5

  Models matter more than harnesses, but experimentation still matters: They prefer different setups like OpenCode or Pi, yet both argue 90% of the value comes from the underlying model, with concrete differences like Opus being stronger on front end and GPT-style reasoning models stronger on back end.

• 6

  Smaller teams and 'agentic companies' are the organizational consequence: They point to Block, Meta, and broader US restructuring as signs that bigger software teams are losing their rationale, and that companies will need to redesign workflows around agents, not just add AI features to products.
