So far everyone I have met with traits like - produces working feature/code faster than anyone else - delivers stable massive projects on time - can carry a whole team through fire and hell - praised to produce masterpiece*
Are the same people everytime who are just - good at playing office politics - are excellent at cutting major corners - knows when their project will fall apart and leaves before - are in league with upper management, so can't callout
I have yet to met a real developer who when left team/project/job didn't leave a massive trail of destruction but up until they were present everything was a-ok-top.
May be someday I aspire to meet one, but so far, most pseudo 10x are just people knowing how to play right politics and hide the skeletons really well :(
