The argument in the above post would not classify those as 10x programmers. antirez is claiming that high quality design and a commitment to simplicity is a big part of what makes some programmers do much more productive.
What slows down my productivity more than anything is looking at someones code and thinking "Why did they do that?" Simplicity pay off in the long term.
However in reality, and what my comment was referring to, is that every sizable team has that one dev who rattles off code quicker than anyone else. Yes it works, but it will have a lack of comments, or they don't check in often enough resulting in merge issue or worst of all they implement a design pattern no one else has heard of.
