It takes a certain type of person who has the grown a sense of technical entitlement and the necessary confidence to believe they're right and that they belong, even when Linus is making up a dozen colorful insults for the things they've done. That certain type of person could be anyone, but there is a strong bias towards those who can find role models that resemble themselves, those who were encouraged and had the resources to get into tech at a young age, etc.
