Remember, for 5,000 years people probably rode those horses. They probably felt that horses were a permanent part of civilization. Everybody has had this moment.

There is a desire for change. There is a millennial generation that doesn't like what they're seeing, but doesn't quite know what the solution is.

I would point out is that most of the change over the past 5,000 years has been arithmetic, and it now logarithmic. Digitization, the whole Moore's law thing where it doubles every 18 months - that is a speed that is faster than most people are used to.

In each business, there is a process, or a delivery system or information system, that is changing rapidly under them.

In most industries, technological change is happening at a rapid rate. I find it is happening in different ways to every industry in the world, and positioning yourself for that, and trying to get ahead of that, is a big conversation right now. Digitization has created opportunities for everybody to accumulate information in a way they were never able to, and analyze it with a speed that just wasn't there.

By the way, I'm not sure the managing director who was 50 in 2005 understood that the job had changed - that when he or she came out of school in 1986, that it was different. How would they know? We've got to admit that.

If you're not exposing yourself to a non-consensus view somehow over the course of a day, you can reject them, but you should expose yourself to them.
