Obama celebrated his election victory this week by immediately tweeting an emotional photograph of him and his wife, Michelle, embracing, and it has become the most re-tweeted picture in history. That’s partly because it captures his humanity and the sincerity of his love for his family, his wife and daughters, to whom he paid lavish tribute in his eloquent victor’s speech.

It also indicates the nature of his support: younger people who tweet, as opposed to older folk who go hunting. Obama is on the right side of history, and that includes the technological future. In this election, the America of Steve Jobs defeated that of Donald Trump.
