Do you really think that Elon Musk's contribution to electric vehicles is comparable to Jobs' contribution to smartphones?
Steve Jobs worked on personal computers before they existed. He was recognized as a visionary with his first iconic device, the Apple II, and he make a huge impact on computing with the Mackintosh which came out in 1984. The list of ground-breaking devices which he worked on is longer than anyone else's. Almost everything he did between the days of solder-yourself computers and the point when everyone had a camera/internet/voice/video/touchscreen-enabled device in their pocket was pushing towards making personal computing and networked communication easier, more user-friendly, better designed, more reliable, etc.
