Until you can do that, you'll always be a lesser software developer. You'll concentrate on maintaining your ego instead of developing the best software for the problem at hand. In a way that's the gist of the article.
It's interesting, but at the company I've worked at, where we've had dozens of senior developers come and go, we've never had this problem. Our approach to code reviews is purely educational. "Here's how we do it so we have the least amount of trouble understanding each others code." Everyone seems to be good with that, and egos get left at the front stoop. I've learned lots, I've taught lots, and I've never felt better than anyone or worse than anyone. It's all about the learning.
And let me tell you, when you hire some junior dev, and he gets these code reviews, and 3 years later he's a senior dev and anchoring a project, it's a pretty good feeling. I think better than any feeling you can get from lording knowledge over others.
