Agent PRs up 9x in 8 months on GitHub: the 2026 tech industry snapshot
The Pragmatic Engineer · rss · 2026-10-07
The Pragmatic Engineer's keynote-based snapshot of the 2026 tech industry, based on visits to OpenAI, Anthropic and exclusive data from GitHub, Factory AI and Linear.
- Unprecedented speed: Martin Fowler calls AI "a whole size difference" from any prior shift.
- What changed: almost nobody hand-writes code anymore; top engineers run 5-10 parallel agent sessions (Claude Code creator Boris Cherny, Cockroach Labs' Peter Mattis, Linear's Dima Zaytsev); agent-authored PRs grew 9x in 8 months, exceeding human-authored PRs on GitHub since August 2026 (75M+/month); Linear now sees more agent-created issues than human ones since July; 83% of Factory AI users use skills, up 2.5x since February; the IDE is fading.
- What broke: assumptions about code output, code reviews becoming theatrical, quality and reliability down.
- What stayed: teams and planning still matter; non-engineers still don't ship code.
- Next: cloud coding agents and harnesses, engineers reading code less, companies building new AI infra.
