What's very weird is that this study was published by two people working professionally at Okta. Yes, the auth tech company.
This is the title they chose for the study:
Beyond the Hype: The Efficiency-Throughput Gap with GitHub Copilot
How can you possibly have a title like that when the study was done in 2024? I'm guessing even their own engineers at Okta would roll the eyes at this study.
