When Robots Feel Sadness
It was mechanically and scientifically impossible. Not only were they hardwired to obey, nothing in their programming allowed for emotion.
For that reason, seeing the robots so sad was a bittersweet experience for Dr. Hoenig. In some ways, he wished they’d never been built at all, knowing how miserable their existence had become.
We can see that Dr. Hoenig is a generous sort. Most people cursed the robots and their overlord ways. Only someone of such a scientific bent could feel empathy for merciless machines that felt unfulfilled because enslaving the human race had not proven enough of a challenge.
