> Productivity was tracked through metrics such as completed tasks (pull requests), code commits, and successful builds.

Making untested garbage faster to check off tasks quicker. Reopen rate please? New bug task rate? Nobody looked...

> The study also monitored code quality via build success rates. Importantly, increased productivity did not come at the cost of more errors, showing that Copilot helped developers code faster and more accurately.

It builds therefore it works. And the test suite was also AI generated?

Feels like we're back in primary school learning programming.

Classic case of gaming the metrics.
