The ones that let other people do the work or the people who do the work themselves? A lot of prominent folks in the Python space are the former.

levels.fyi gives $650k in SF. But it looks quite low to me. I'd have say 1M/year at least. Any better guess?

I think you're right. The issue is, due to the power law distribution of talent, the sample size of such roles (and personalities, i.e., how many Python BDFL's are there?) is incredibly small, so it makes precise assessments difficult and the variance increases wildly since there aren't very good comparables.

I think he could command nearly $10 megabucks, give half of it away to charities, grants, scholarships, social ventures, and underserved areas to promote STEM college prep, and still have more money that one ostensibly average, middle-class person would know how to invest (real estate on the near periphery of burgeoning urban sprawl areas). Microsoft is a cash cow and is willing to invest in a solid, deep bench to stay competitive, especially in an apparent transition to either EEE or adopt OSS.

Someone else commented that he'll be Distinguished Engineer (DE). But levels.fyi shows 69, the level under DE, some reports of 1-2m. He's almost assuredly receiving 1-3m compensation.
