> As an aside, I know tons of experienced "Senior" developers who just suck at their jobs. The problem is they have tons of experience in delivering terrible products based on terrible code and architectural decisions.

It's a classic tragedy of engineering; you can actually ship with almost anything, and just successfully delivering a product reinforces a feeling that your choices were good, no matter how arbitrary they were in practice.

People can get really confident that what they're doing is tried and true, while it's simply the only approach they've had for all of their career.
