I find some of the 4GW points interesting (mostly those articulated in "The Sling and the Stone," though I have reservations about his reliance on Mao), though overall I don't consider it a credible "generation." IMO what we're seeing is a convergence of 3GW with older terrorist tactics and an acceleration of media attention due to technological advances. I would say it's more of an advanced 3GW, but not the sweeping thing that 4GW advocates claim.

Also, I think there's a fair amount of ego invested in 4GW.
