“A robot may not injure a human being or, through inaction, allow a human being to come to harm.”
Both the later books, and the Will Smith movie explored the logical conclusion of that law: to protect humans against themselves, robots would have to take control

“A robot may not harm humanity, or, by inaction, allow humanity to come to harm.”The Robots determined that letting humans know they had been influenced could cause harm.
