You characterization of Marc Brooker as a "confident beginner" is incorrect. The guy is a senior principal engineer at AWS, was the leader of EBS when I interacted with him, and has built more systems than I care to mention. The phenomenon he is describing is totally real. Of course the article is a simplification that attempts to isolate the essence of a terrifyingly complex problem.
And it even says as much in the sidebar on that page:
> I'm currently an engineer at Amazon Web Services (AWS) in Seattle, where I lead engineering on AWS Lambda and our other serverless products. Before that, I worked on EC2 and EBS.
