I felt it funny, because this is so like debugging, it's like watching a testing/debugging tutorial.... every story is kind of like some robot issues were found and they were trying to design some tests and find out which part of the laws was making it do that. Later stories have some more about how the Laws are logically preventing misuse. I do feel it may be a bit too optimistic to believe under the three laws there is no way the robot could, as the story where the first law was changed said, hold grudge, believe in its own superiority, start a religion and a revolution. I doubt if human could make the robots that can and will always make better - more morally correct - decisions than humans do, with the laws.

But on the other hand, I suppose in that story, she was just trying to take a chance. She was doing some believing in her part too.
