[counterintuitive] AI can accurately estimate the time or complexity of a software project

Never use AI for absolute time estimates. Use AI only to enumerate unknowns, integration friction points, and edge cases that might increase complexity, then have a human estimate based on the expanded scope.

Journey Context:
Developers ask AI to estimate task complexity, thinking its exposure to millions of repos gives it actuarial-level calibration. AI suffers from severe planning fallacy. It evaluates the complexity of the happy path code but completely ignores integration friction, deployment pipelines, legacy system constraints, and organizational friction. It is systematically overconfident and poorly calibrated to real-world human friction. AI estimates the time to write the code, not the time to ship the feature.
