Does anyone doubt that there are 2x programmers (programmers twice as effective as an average senior developer)? I have worked with a number of them. If one were to assume some sort of power law or Gaussian tail distribution, it is logical to assume that a few 10x programmers exist. However, they are going to be sufficiently rare that you are not likely to be able to find them or recruit them. A more interesting question is if there are 3-4x programmers, and if so, is it feasible to find and recruit them? I have worked with people (rarely) that I would consider 4x programmers.
