Paging Isaac Asimov

The 3 laws of robotics are:

1. A robot may not injure a human being or, through inaction, allow a human being to come to harm.
2. A robot must obey orders given it by human beings except where such orders would conflict with the First Law.
3. A robot must protect its own existence as long as such protection does not conflict with the First or Second Law

So now what? Elon Musk things we a summoning the devil (que Skynet!). Either way we have to consider what the consequences are of our creation.
