TED should invite a Mafia Don as an example of a really radical leadership style managing change in a fast moving environment.
This goes to what TED stands for - I think the morality of an enterprise should be a factor in whether a representative is invited to speak, and I believe the military is basically immoral.
Would TED invite a cutting edge researcher on germ warfare or remote controlled weaponry just because they are good at it?
If anything, surely TED should be promoting the redistribution of the vast military budget towards more socially useful ends. It would fund all the R&D ever mooted on TED for several decades.
