# Will The Bitter Lesson Obsolete Harness Optimization?

## The question

Will future generations of foundational models become so capable at navigating messy codebases and inferring intent that the ROI of meticulously engineering custom skills, sandboxes, and clean architectures diminishes to zero?

## Why it matters

This is the principal counter-pressure to Pocock's entire thesis. If [[entity-the-bitter-lesson|Sutton's Bitter Lesson]] holds, then the time and effort invested in [[concept-ai-harness]], [[entity-sandcastle]], and [[entity-matt-pocock-skills]] could be largely subsumed by raw model capability.

## Resolution path

Observing whether future foundational models (GPT-5, Opus 2, and beyond) become capable enough at:

- Navigating messy, undocumented codebases.
- Inferring developer intent from minimal context.
- Self-correcting without test seams.
- Operating safely without sandbox isolation.

…that the relative ROI of harness engineering visibly diminishes.

## Likely partial answer

Even if model capability grows, harness work in safety-critical, regulated, or auditability-sensitive domains is likely to remain valuable. The question is really about the *median* developer's ROI, not the upper bound.
