There is a shocking amount of ad hominem and focus on the years of experience in this article. Are people actually reading the article? Perhaps surprisingly, it's really fucking good. I'm absolutely planning to share this with junior devs that I work with.
Author may not realize how much more there is to learn than he already knows, but we all kind of have that problem, just at different scales, am I right? He's doing all the right things, learning the right lessons, and is on track to be senior whether he has that title at work or not.
