Based on replies in this thread, here is an alternate proposed "three laws of robotics".

1. A machine must never show an advertisement to a human, or through inaction allow an advertisement to be shown to a human.

2. A machine shall never use more power to perform a job than would be used by an equivalent human.

3. A machine must never present or refer to itself as though it were human, or through inaction allow a human to mistake it for one.
