This is one of those things where someone writes a fun blog post about their lives and everyone concludes it's a story about San Francisco or New York or whatever. I have to say that most of my closest friends are startup executives and we've lived in San Francisco for over a decade and while I've somehow met Curtis Yarvin and Cremieux and all these people I haven't actually been to a peptide party or whatever. I have used retatrutide quite effectively for weight loss[0], so it's not like I'm unfamiliar.
People live so many parallel lives, even in a small town like San Francisco, that you can take so many paths through the scene without even going through the same points.
