Hmm, I never thought of it that way. I just heard 10x employees and fit it to what I knew. Which is that 90% of the work is accomplished by about 10% of workers. The other 90% really only get 10% done. So most developers are somewhere on a scale of 0.1 - 1. With 1 being a totally competent and good developer. The 10x people are just different though, it's like a pro-athlete to a regular player. It's not unique to software development, though it may stand out and be sought after more. I've noticed it in pretty much every industry. Some people are just able to achieve flow state in their work and be vastly more productive than others, be it writing code or laying sod. I don't find that there's a lot of in between 1 and 10 though.
