Will human beings be replaced by robots?

The answer is it might be possible, but hard to say. Nowadays with the fast development in artificial intelligent and robotics, there are a lot of human jobs replaced by robots already. For example, in the factories, robots have been widely used to make parts of machines, packaging product goods, or conducting accurate operations. Human has limitations in many areas, and those heavy labor jobs are usually replaced by robot machines. 

However, human beings still have very complex brain and nerve systems. AI development can try to approximate human beings, but can they ever exceed to achieve the limit? We will wait and see.
