On "just partying", while I get what you're saying, I have a hard time to believe they ever cared about what HN thought about them or that our opinions had meaningful impact. TBH I am/was more jealous of people with truly advanced "people skills" than anything, especially as they still earn pretty decently.
Lots more money is still made by networking or potentially mild grifting than through sheer innovation or technical excelence for instance.
