I read somewhere that 100% of YC winter 2023 branch had an AI angle which was really sad to read. You have the most well respected and exclusive VC and its investing in mostly companies that are thin wrappers and integrations around an LLM they don't own.
Your mistake was assuming YC cares about "true" value and not (a chance of) monetary success. YC may look all nice and have a decent PR team (and some/many people may genuinely be nice folks) but they're just a business at the end of the day.
