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.

Law 2 is per Amy Worall, law 3 is per the Witch of Crow Briar.

I do not endorse these laws, but I would consider them "utopian", in the sense that a culture which endorsed these laws would be a culture organized along a clearly-formed ideology. You could easily imagine a spec-fic story about a culture that believed in these laws. Note these laws are necessarily laws for human designers, as the existence of a machine which can enforce them is ideologically inconsistent with law 3.
