At MIT, I had the good fortune for seven years to teach network theory, which is basic to many disciplines, to one-third of the undergraduate student body. It was an experiment to see how high we could bring their level of understanding, and it exceeded all of my expectations.

I'm forming a charitable institution for education.

The excitement level for me working on projects is really not a bit different from when I was 26.
