I don't understand your comment. Most geeks are not "bros." As you say, most of us don't fit the "bro" profile. There's no conflict here, there's just different names for different groups of people.

It's a sub-category of "Silicon Valley programmer/entrepreneur/founder". Awkward geek is one sub-category, "brogrammer" or "tech bro" is another sub-category. They're separate stereotypes for the same career.

I think there are far more geeks in Silicon Valley than there are "tech bros", but the bros certainly exist.
