Why? Tell me a better way to fight an enemy that uses civilians as camouflage.
The biometric stuff just seems too dangerous to me, and unlike e.g. Nuclear arsenals, there's no peaceful game-theoretical equilibrium at MAD, I just see an extremely effective tool for the eradication of groups of people, and I don't trust human beings not to misuse that, especially with machine intelligence getting so powerful so fast.
It all feels frighteningly unstable to me.
edit: A perhaps more lucid way to explain what I mean: I am afraid of a world where the cost of eliminating a group of people is low enough that it outweighs the incentive to adapt & negotiate peaceful coexistence, even without what I see as an innate human bias towards destroying groups we don't like. Do violent, authoritarian regimes begin to gain an edge over peaceful, democratic ones?
He said that the USA method is to go to some village, kill the head and say "now you have democracy, elect a new leader", and chaos ensues.
While our way is "we build you a well and a road, let us know if someone comes to recruit young people".
Of course since the USA soldiers are the most, their way is the one that happens more often.
At this point you can just shoot at anyone and say "terrorist".
