you're right. Yet what do you want from an ape species who makes beheading videos and posts them on entertainment sites? There are huge chances that we may be at some bifurcation point before very possible fall into Dark Ages or into collapsing into a planetary-sized self-centered ant colony (which i think is among the main traps what most early technological civilizations in the Universe fall into (other trap being of course is an all out nuke war)).
ISIS and their ilk are such a small percentage of what humanity is all about. Don't look at them and think that we're moving towards a new Dark Age. Life in much of the world is as good as it has ever been.
