This is a great point and I think it’s because I’m not sure that I personally know any tech bros. There probably are tech bros, but I know a ton of people in Silicon Valley pretty well and I can’t think of any right now. I’m actually wondering if “tech bro” is just an otherizing stereotype like “Bernie bro.” I’ve known a large number of supporters of Bernie Sanders for President, many of them old ladies, but I’ve never met a Bernie bro. On the other hand, perhaps this all means that I’m actually what’s known as a tech bro myself and I just don’t realize it.
