The Marginal Cost of Correctness

The Marginal Cost of Correctness

Tech X
As AI agents lower the cost of generating syntactically correct code, engineering value is shifting from implementation speed to critical oversight and systemic intuition.
What: Benjamin Glickenhaus argues that basic code generation is becoming a commodity, necessitating a shift in focus toward architectural judgment and detecting subtle, non-obvious logic errors.
Why it matters: This signals an industry transition where the ability to 'write code' is becoming secondary to the ability to 'verify and design systems' in an era of automated synthesis.
Deep dive
  • Code generation is increasingly automated by LLM agents.
  • Syntactic correctness is no longer a professional differentiator.
  • Senior engineers must focus on architectural 'smell' and complex system integration.
  • The bottleneck in development is moving from writing to architectural validation.

The Marginal Cost of Correctness

The marginal cost of correctness is going to zero. You need to internalize what this means for how you practice software engineering. You need to be obsessed with doing things correctly.
