One of my co-founders made a really interesting observation the other day... the 10x programmer often gets his 10x by leeching the performance of other team members. 10x programmers don&#x27;t talk through their decisions with teammates, or think about the consequences of their rapid changes on other members, or indeed, the long-term health of the project.<p>If a 10x programmer turns a 3x team into a 1x team, that super-genius isn&#x27;t worth having.<p>And this is why I hate working with primadonnas who think they&#x27;re brilliant.
