> Yes, technically. But practically, every single story showed how some robot was able to reason his way into violating the spirit of the laws.

Huh? There is literally one story (Little Lost Robot) where there is a "loophole" in the laws (and only because the First Law is modified to drop the "or through inaction allow a human to come to harm" bit).

EDIT: in thinking about it further, I guess I'd add That Thou Are Mindful Of Him to the list of "loophole" stories. Still, two examples out of dozens of stories is very much the exception, not the rule.
