Surely, this is another trash blog post trying to prove something without doing any work or even defining a goalpost of "better programmer". e.g. "It’s also not true. That inadequacy you’re feeling is based on false assumptions, a misunderstanding of the skills it takes to be a good programmer." - 0 citations. The post is a contrarian thought experiment, I think.

My belief of the opposite conclusion (from the blog post) is based on a simple axiom. You have restrictions at work. Negotiated technical, and practical (different than those at another location) restrictions. Limiting development to one location necessarily makes you less flexible in thought and skill and practice. This is commutative (the person with 5 years development in school, entering the workforce).
