Science fiction writer James P. Hogan wrote about this in the Two Faces of Tomorrow. In his book,the Earth's interconnected AI machines could not recognize people as fragile objects to be protected,they were as very young children that did not know any better. the Number One Sci-fi writer Isaac Asimov also addressed this in his Robots novels, long ago he created the Three Laws of Robotics to deal with it.

Asimov's Three Laws of Robotics;
1.A robot may not injure a human being or, through inaction, allow a human being to come to harm.
2.A robot must obey the orders given to it by human beings, except where such orders would conflict with the First Law.
3.A robot must protect its own existence as long as such protection does not conflict with the First or Second Laws.

these laws still leave a lot of loopholes.

the far-sighted Asimov also addressed the concept of robots doing everything for people,and the people and society declining as a result.

As robots keep replacing human workers in manufacturing and now retail and food servicing, fears have arisen that artificial general intelligence (AGI) machines will  threaten mankind when "intelligence escapes the constraints of biology" and machines can design and create their own offspring.

If that idea sounds far-fetched, then please consider Cambridge boffins fear 'Pandora's Unboxing' and RISE of the MACHINES.
