Is the drive-thru 3 laws safe?
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 I pull into a drive-thru and order a Big Mac, large fries, and a milkshake. The AI goes processes the orders, and then looks at me. It notices I might have a slight health problem. If the AI does nothing, my health might be harmed by my order. So, for the good of myself, the drive-thru AI modifies my order. Instead of a Big Mac, I get a basic hamburger. Instead of a large fry, I get a large salad. Instead of a milkshake, I get milk. The next person in the drive-thru queue approaches. The AI notices that this person has been at McDonald's before, many times before this very week. It also notices that the person has a severe weight problem. Based on what the person ordered last time, if the AI allows this person to order, it certainly will harm the person's health. This person begins to talk to the AI, but it says "I'm sorry, we are currently down for maintenance."
A 3 laws safe drive-thru could really help our health!
