[counterintuitive] AI is broadly better than senior engineers at coding; the gap is just model scale

Assess tasks on novelty \(ν\) and verifiability \(v\): delegate low-novelty, high-verifiability work \(routine code with tests, docs, boilerplate\) to AI; keep humans on high-novelty, low-verifiability work \(architecture, product strategy, ambiguous debugging\). Empirical data show AI accelerates routine tasks but can slow experienced developers on novel, mature-codebase tasks.

Journey Context:
The 'AI will replace seniors' narrative ignores task structure. The novelty-verifiability framework derives that human effort scales linearly with the novel fraction of a task; high verifiability only reduces the coefficient. This matches METR's 19% slowdown for experienced maintainers and Copilot's gains on routine tasks. Senior engineers' value lies in shrinking ν for others by writing conventions, tests, and architectures, not in being displaced.
