you raise a valid point about survivorship bias I guess, but as of the last few years it seems a lot of rage bait and do anything to get signal instead of the positive optimism that I felt a lot of the companies offered those years ago. i guess what i'm trying to say is that it has become the final version of itself as a venture firm, whereas before it was quirky (again, I am outsider!! so this is my POV) and backed companies that made products/services that I think made my life objectively better.
end of the day, I really like YC and think they do a good thing overall. but I think people/founders have realized how to game it, if that makes sense.
