10x being real or not aside, if there's a 1x-type they certainly don't do many of the things in this list in my experience and certainly not:

>Writes code that others can read.

>Reads the Docs.

>Updates the Docs.

In my experience, half of the differentiation between above average and solidly "1x" or middling devs is reading documentation and obtaining a deeper understanding of the tools, language, platform they're developing on top of.
