P. W. Singer quotes:

What one Predator drone pilot described of his experience fighting in the Iraq war while never leaving Nevada: 'You're going to war for 12 hours, shooting weapons at targets, directing kills on enemy combatants. Then you get in the car and you drive home, and within 20 minutes you're sitting at the dinner table talking to your kids about their homework.'

Robots are emotionless, so they don't get upset if their buddy is killed, they don't commit crimes of rage and revenge. But ... they see an 80-year-old grandmother in a wheelchair the same way they see a T80 tank; they're both just a series of zeros and ones.

The drone war takes place 24/7, 365 days a year. The war doesn't stop on Christmas. It's like being a fireman when there's a fire every single day, day after day after day. That's emotionally and physically taxing.

Drons change the way politicians think about war. You already have society's barriers against war dropping, and now you have a technology that takes the barriers to the ground. We can carry it out without having to deal with some of the consequences of sending our sons and daughters into harm's way.

When a robot dies, you don't have to write a letter to its mother,
