"Gates, or Zuckerberg" Perhaps not as a programmer but as a business person? Gates (along with IBM and a zillion other things coming together at the same time) have allowed the popularization of computers and reduced the cost to allow many things to happen as a result of what they have done. Think of medical advances as a result of people who were able to cut their teeth on computers and/or components dropping in price. If no PC, no YC or PG and all that follows from that. Etc. Things invented lead to other things. In that sense even Zuckerberg has changed the world by the associations that people have made that have lead to something because of who they met or became friendly with on Facebook. The question is really how do you define "change the world"? And how do you separate one persons involvement from just what happened to be around at the time and would have happened anyway had someone else done it first?
