History is not so simple as this guy points out. Jobs had a significant impact, no doubt.
People like Carnegie were not so nice, nor Rockefeller, Edison, Khan, Atilla the Hun. However, history remembers these people just fine, for good and bad.
I believe it's quite normal to see the good and bad in people, because in reality that's how we all are. Jobsy left on a high note, turned Apple around. He will be remembered - and fondly, might I hazard a guess.
