Re: Before we worry too much...
"It's not logical to assume the use of AI would encourage or lower the threshold for the use of lethal force. It's entirely possible to create an AI with conservative firing permissions rather than being at the go-ahead of a potentially excited, possibly blood thirsty, maybe mistaken young man."
It's not the front line troops decision making they are worried about, it's the political leaders decision making.
The reasoning is, drone warfare will be much cheaper, both in terms of less service personnel being killed and injured (creating bad headlines at home) and in terms of resources needed to carry out a campaign (less personnel in the field means less logistics needed).
The fear is that drone warfare makes the idea of waging a war more palatable to the politicians and hence make armed conflicts more likely to happen.
