If you want a description of me, a person once came up to me saying that they had been told to look for a six foot nerd with glasses and I seemed to be the best fit in the room. (This really happened.) I live near Philadelphia, PA, USA and have a degree in Chemical Engineer with a few decades experience in computer programming.
I decided to ask for posting privileges so that I could mention the short story Little Lost Robot by Isaac Asimov
https://en.wikipedia.org/wiki/Little_Lost_Robot. It appears to be relevant to the Kusari discussion since it explains how a robot with a weakened first law can kill a human being without violating the rules. It is very similar to some of the discussions currently on the forum.
