A robot may not injure a human being or, through inaction, allow a human being to come to harm.
A robot must obey orders given it by human beings except where such orders would conflict with the First Law.
A robot must protect its own existence as long as such protection does not conflict with the First or Second Law.
Scratch the word robot and replace with with human. Then we might have something applied to people not harming people. Maybe we can learn how to not to harm one another this way.
Every post I create I hope it makes sense to my followers. Those posts make sense in my head but they can come across a little wonky on the screen. Keeps the reader on their toes I suppose.
