> I've contributed millions of lines of carefully written OSS code over the past decade
I have never tracked my own output, but I would be surprised if I have written even a single million lines of code, let alone several.
Out of curiosity, is this common? Have people here actually written millions of lines of code themselves? Even assuming two million lines over thirty years, that still averages to around 180 lines per day, every day. It is doable but it is a very high level of sustained output.
I am not doubting the OP. Just noting that this represents an extraordinary amount of coding by any measure.
