Here's an amusing / dismaying screen capture of young adults wondering who the heck this Bin Laden guy was...
On the one hand, it points to a dismal knowledge of world affairs and recent history.
On the other hand, it points to the fact that Bin Laden had ceased being the great public mouthpiece of jihad. Even if he was still pulling strings behind the scene, he no longer loomed quite as large in the public imagination. Despite all that bluster about "loving death," he was hiding in a safe house from those who wanted him dead.
When he was fighting, he might have "died a martyr."
But after all this hiding, that's a non-starter.
