That has not been my experience at all with "10x" programmers. I have often run into the first type from the parent comment - "hyper-productive" people who churn out huge amounts of code without a lot of thought. They tend to leave side effects all over the codebase, and often have someone in management who sponsors them (hoping to ride to promotions as a pair) who forces other teams to carry the burden of cleanup. However, if you run a startup, this kind of person really is an amazing asset, because there isn't a lot of codebase to clean up.
People I have met in the the third type (true 10x-ers who know it) seem to have a lot more humility, in my experience, than suggested here. If you look solely at metrics like kLOC/year, they are often in the middle or bottom of the pack. They are not usually generalists, instead specializing in some area that is of high value.
I’ve seen it many times. I’ve even seen managers on teams try to sabotage a 10x:er because he made the manager (and team) look bad.
When a single individual outperforms a large group the large group typically doesn’t like it, or the person doing it. Sadly that’s just a part of human nature. Where I live (Sweden) it’s referred to as the law of Jante. In other parts of the world it’s referred to as tall poppy syndrome or crab mentality.
