My main beef with the article is that it ignores career progression. The article is focused on coders and their interactions with each other and with customers. In practice, that kind of work is done by the folks in the trenches.
However, advancement is important to many people, and those that climb the corporate ladder surely leave actual coding behind – that’s done by the employees that they manage. Without saying so, the article is evaluating the “loner genius nerd myth” with respect to newbies and career coders – only a subset within the CS corporate culture, I believe.
