HN and YC walk a thin line between hacker culture and venture capitalist culture. I know it’s easy to think that because HN comes from YC them too are aligned with hacker culture, but no. YC is all cutthroat business.
HN is deeply skeptical, technical, cynical, sarcastic. It's a great place to learn new things and I've loved it since I found it in 2012.
The current startup climate (not just limited to YC) feels very AI bro YEAHHLETSFUCKINGGOO (and I say this as a founder myself having gone through YC recently in W25).
