Your comments gives the impression anyone could have substituted RMS place in history. I want to point out that this is not the case. RMS is unique in at least 2 ways. One his intellect stands out even among the 100x programmers. Second willing to sacrifice his personal life for a cause he believes in. Its very rare both intersect. You can see either Einstein level geniuses or Activists who sacrifice their personal life. RMS is an intersection of both. The only other person I can think of is Aaron Swartz.
