The 10x person fits very well in their organization. They are admired by upper-management for their ability to quickly comprehend, estimate, and deliver solutions to problems. They mentor everyone that asks or needs help. They provide 95% test coverage on all code. They show up for work well dressed, clean-cut, and on-time every day. Their code isn't 'brilliant' because they understand it must be maintained by the whole team. Their code reads well across difference experience levels but also includes clever tricks. They have an absolutely rock-solid understanding of the operating environment, platform, and modules. They don't document their code. They are the smartest person you know.
The 100x person seems to fit very well into the organization at first, and appears to be a 10x. They take on several seemingly-impossible tasks up front and eat it for breakfast. They automate large portions of the business and their own processes. They provide 99% test coverage on all code. They create production-quality docs after their public interface solidifies. They know security and implement it correctly. They spend months to years on self-driven projects to master different categories and build their tech-tree. They have invented tech and patented it. They bump into the intentional barriers of the organization. They break through and create a billion-dollar product, or they are removed from the organization. They are the smartest person you know and without explanation they appear to be insane.
It really seems 10x is a stigmatized term. It used to mean a developer that could produce 10x lines of code, but at this point I've taken it to mean a single developer that can leverage technology, their department, and organization to manifest a 10x positive impact compared to someone just cashing their check delivering story points. I don't think this term really fits for someone on the spectrum wreaking havoc in their organization.
