When I was a kid I read Asimov's laws and it inspired me to work on robots and machine learning. However, I quickly realized: the computers of the time (Apple IIe) could not implement those laws; they required the ability to parse human text, and more importantly, my read of the laws and how to comply requires the robot to create an accurate predictive utilitarian model of its actions and their effects. And be able to continuously re-evaluate that model and choose actions consistent with the laws.

After looking more into utilitarian models, I concluded there was no way to implement Asimov's laws unless you had a superintelligent AI. But in retrospect, I think I was interpreting the laws in the 'hard' form.
