22.7%Share of defects remaining after AI correction

PHYSIX OBSERVATION

Model unit prices keep falling, and enterprise book costs do look good, but the human labor for debugging AI code, acceptance testing, and long-term maintenance has not disappeared; it has merely moved from the bill into hidden expenses. More alarming is the contraction of entry-level positions and the talent pipeline gap: the wages saved today may have to be repaid years later through a more expensive mid-level shortfall.
