IMO being "10x" or whatever is not really about productivity or skill, or rather, those are necessary but not sufficient. What it really comes down to is doing the work that makes other developers more productive. In other words, the 10x developer doesn't output ten times as many lines of code or complete ten times as many stories. They simply make everyone else's life a little easier by identifying and working on the important stuff.
