I have to disagree on this one. If there is one who does not belong in the list, it would be Knuth. Zuckerberg, as well as Gates, Larry and Sergey, has created a technology company that changed the lives of millions. They are all well known by the "civilians". Torvalds less so, but still, the Linux project has had a relevance that trascends beyond mere technology. Mr. Knuth's contributions, on the other hand, are much more fundamental. But, because of this, his name remains unknown for the general population. For us, he is a titan amongst men; for the world, he'd be an old, retired professor who cannot even figure out email.
