Eric S. Raymond talks a lot about about his importance, but in reality he has produced no software of value, in fact almost no software at all. The arrogant statement he made in the beginning of the interview is a blatant lie:
> You rely on my software every time you use a browser, a smartphone, or a gaming console.
I think he's referring to giflib or pnglib there. Those libraries are fairly widely used in many places and is probably the most widely used code he is associated with. That said, he is fairly egoistical. I don't think even he would deny that.
Well, I checked pnglib for one. He is one of 20+ contributors, not an original project founder, and was only active on it for like 2 years (2000-2002 IIRC):

ESR is known for his books, not for his code.
