AI now writes half of what goes into Linear. Teams tripled their pull requests. Linear itself says it has no idea if any of that helped.
The viral headline says AI made teams slower. Linear's actual report never measured shipping speed at all.
"AI now writes just under half of all Linear issues, teams that connected a coding agent tripled their weekly pull requests — and total product development time increased anyway." [SOURCE ↗]
THE CLAIM. AI now writes just under half of everything created in Linear, teams with a coding agent tripled weekly pull requests from 21 to 65, and total product development time increased anyway.
THE CHECK. Linear's own data report backs the first two numbers, verbatim. The third doesn't exist in it. What actually rose is "time spent creating, triaging, and commenting," Linear's own words, for time logged inside the issue tracker, not time-to-ship. Linear has never published a cycle-time or time-to-merge number in this report.
THE TWIST. Linear says it plainly: "we have no way of knowing whether this increased output led to positive business outcomes." A separate dataset of 8.1 million pull requests found AI-assisted PRs merge at roughly half the rate of human-written ones, meaning tripled PR volume isn't tripled delivered work. Three more PRs a week and no faster ship date is not a contradiction. It's coordination overhead with better marketing.
PR count and issue count are activity metrics, not delivery metrics. If your team's dashboard is bragging about AI-driven volume, ask what happened to cycle time before you believe the volume meant anything.
The next viral "AI slows teams down" story will trace back to the same move: a volume metric relabeled as a speed metric. Watch for it.
Flips if Linear or a comparable tracker publishes an actual cycle-time or time-to-production metric showing AI-adopting teams shipping slower, not just logging more activity.
