I was invited to write an essay on technology for “Scientific American.” I have not yet seen the issue so am not sure who else contributed. When I was invited, I was told that there would be articles by Bill Gates and Arne Duncan. As you know, there are a few differences among us. One of them is that I write every single word that is published under my name. No one else writes my books, articles, blogs, tweets, speeches, or anything else.

Here is the article in “Scientific American.” Let me know what you think.
