AI-generated PRs now 3x human-written on GitHub — but one number hides too many dimensions

Gergely Orosz cites data showing GitHub now sees more AI-generated PRs per month than human-written ones — roughly 3x by end of 2023.
Data scientist Neal Lathia pushes back on the aggregate figure: he wants it cut along dimensions like fully vs. partially AI-generated, number of concurrent sessions, whether changes are related to the project, and whether they're predominantly bug fixes or new features. His take: nobody has the full picture — surging PR counts don't mean proportional engineering value, and the denominator likely hides plenty of noise.
