EDIT: I'm not saying that Valve's flat hierarchy is a lie or something like that, but I'm just referencing a different point of view about the whole thing, which is a nice reference.
Nice read. Keep in mind that it is from within Valve that she created the castAR technology. Valve's culture allowed that to happen. If she were in another company, perhaps castAR would have never been born.
Clicks will happen in any social structure. Even more so in the traditional hierarchical structure. This is why there are people who are good at climbing the corporate ladder. They happen to click well with their bosses (or perhaps intentionally), creating some sort of "we are the cool people, you are not" barrier. They climb up not because of any particular excellence in the field, just because they know the right people within the company, just as the old saying goes that it's whom you know, not what you know.
