Quote - it's not a couple of experts with nothing better to do than recreating bachs face that troubles me, but the legion of experts with nothing better to do than inventing more efficient weapon-systems, which seems to be widely considered as normal and useful.

Weapons are normal and useful.
Long, long history of that sort of thing... it's tragic when the bad guys use them, but pretty cool when the good guys do. Gotta see it in perspective though - a world without weapons is like a world without humans. ;-)
