A fine example of Goodhart's law: "When a measurement becomes a target, it ceases to be a good measurement."

Measuring open source contributions as a way to judge prospective employees used to be a good measurement.

Of course, prospective employees started to not only contribute to OS projects because it was good, but to make sure their contributions were high and noticeable — contributing not for the good of the project but for their own good, and now with amplification of AI 'contributions'.

So, measuring contributions to open source projects is now approximately worthless for evaluating prospective employees.
