Report #83853

[counterintuitive] AI excels at large-scale framework migrations because it has seen both old and new codebases

Use AI for mechanical syntax transformations, but manually verify semantic shifts and deprecated behaviors. AI will confidently map old patterns to new patterns that look equivalent but have subtle runtime differences.

Journey Context:
Framework migrations are fraught with distribution shift—the new framework changed because the old one had fundamental flaws. AI maps the syntax 1:1 because it optimizes for local coherence, completely missing the semantic reasons for the framework change \(e.g., Vue 2 Options API to Vue 3 Composition API reactivity traps, or Python 2 string handling to Python 3 bytes/str\). AI is systematically overconfident in syntactic equivalence.
