But as you will see at the end, my attitude changed and this is the result. I was asked recently whether killer robots could come and kill us all. Not wanting to lose an opportunity of teaching, I asked the question. How would you build a killer robot? The reply I got was I don't know. Well, I said, let's break this down to what AI we already have. Basically, we need AI to identify the humans and to move the robot arm holding the machine gun to shoot at us. We have vision AI to identify the target, the human. Vision AI currently is sufficient to identify humans and non-humans fairly accurately. This would lead to a high accuracy of recognition by the robot. The robot would be able to identify the human when it sees one. Machine learning would be required to find where humans are likely to be hiding. So an AI robot would need th...
