The first deployment of an autonomous 'Border Protector' vehicle has just been made in Israel in July 2016. These UGVs (Unmanned Ground Vehicles) are being deployed to monitor the Gaza Strip border, and the IDF is already discussing plans to add on weapons, and eventually to give the weapons totally autonomous A.I. control.
This will effectively create fully autonomous killing machines.
In line with the Open Letter on Autonomous Weapons (http://futureoflife.org/open-letter-autonomous-weapons/)published in July 2015 and signed by notables such as Elon Musk, Stephen Hawking, Steve Wozniak and 21,000 other concerned citizens, we now call for a complete global ban on the development, deployment and sale of any and all autonomous weapons.
If we do not deal with this potentially disastrous and dangerous issue now, we will inevitably see the start of an Artifically Intelligent arms race, with non-sentient killing machines built and deployed anywhere in the world which has the money to buy them.
