Dennis Ritchie co-invented C which is the basis of basically everything that involves computers. He co-invented UNIX which is the basis of everything computers except Windows (though Windows was very, very extremely influenced by it). Apple's OS X is a UNIX-based platform. But, no, so many people think Steve Jobs did it all alone and that he should be praised as a savior. Not only did he "borrow" ideas, designs, and features from everyone else, he whined if anyone ever did the same. In 1996 he said "We have always been shameless about stealing great ideas." In 2005 he said "They are shamelessly copying us." This year he said "I'm going to destroy Android, because it’s a stolen product. I’m willing to go thermonuclear war on this" and then almost immediately afterward released iOS 5 with a ton of features first introduced in Android. The guy is/was an asshole. I have no patience for a hypocrite like him.
