In an uncharitable interpretation, this is tech/VC returning to the mean -- this is the "good ol' boys club" (the sex of the person in particular is not important) that generally people talk about, and it's how society works most of the time. VC is not charity, they are incentivized to filter, and they do. That does not necessarily mean it's the same discriminatory environment but that depends on the person doing the searching and their ethics/principles/choices.
That said, YC is just about the antithesis of the aforementioned phenomenon -- they were one of if not the first to significantly drop the barriers to accessing VC. They took their program abroad and lowered barriers to entry for smaller international economies abroad. They've upped the amount given to founders and are running hot trying to accommodate huge incoming batches. They make founder school and other resources available absolutely free. YC's made it a breeze to work at any of their companies and get on the hundreds/thousands of rocketships they launch every year, VISA difficulties aside (there was also some mention of them working on a VISA "fast track"-ish path or something).
> It’s just that it feels like if you don’t have the grit etc necessary you’re just out of luck and out of this club and it’s not really something you can work on. (After all if it was something you could improve then it could be taught but PG et al seems to think - and I think they’re right - that it’s an innate thing.)
This is an extremely reasonable thing to filter for -- judging startup ideas is hard/impossible, and with lots of reflection it seems that grit is one of the things that sets founders apart (clearly ideas don't, execution usually will but maybe sometimes doesn't, etc). It makes sense for all VCs to filter for these qualities.
Now where I do agree is that people who can game the system -- but maybe grit is hard to fake. At some point you end up just... acquiring grit, because the situation is hard.
Grit and perseverance can definitely be learned. What it takes to embed it in yourself and motivations may vary from person to person, but it can definitely be acquired most of the time, I think.
[EDIT] - forgot about free founder school and stuff on YT
