Author here. I'm a CTO with 15+ years of production engineering (Scala, Rust, large-scale systems). When I saw the Stripe blog, the number that jumped out wasn't 1,300 — it was 1,300 / 3,500 engineers = 0.37 PRs per person per week.The deeper issue is the industry pattern: every company announces impressive AI coding metrics, and every independent study (METR, DORA, GitClear, Faros AI) shows those metrics don't translate to organizational outcomes. I have a paper under review at ACM Computing Surveys synthesizing 37 studies covering 500,000+ developers — the central finding is zero organizational throughput improvement despite 20-55% individual gains.Happy to engage with pushback.
