1. A hacker ethos from a decade of programming is required to start a company like Facebook.
2. There are few women who have the hacker ethos already
3. YC can objectively determine who has a hacker ethos
4. YC cannot teach the hacker ethos in 3 months
5. This is the main reason YC does not accept many women
I think that there are a number of problems with this series of arguments, some of which are rooted in systemic sexism:
1. There are many great companies started by non-programmers. What PG calls a "hacker ethos" and his decision that it is necessary are both based on observing the output of a biased system that favors white males.
2. This doesn't seem to line up to me. >20% of CS grads are female yet <10% of YC founders are female (lower rate in early classes).
3. We know this is not true, as we all have cognitive biases. Some adjustment for this bias should be implemented if we want to have a fair system.
4. Maybe. But why not even try?
5. See #2. Maybe there is another reason, but this doesn't explain the very small number of female founders on its own.
