Will robots ever become just like humans? | The Register
We are getting very close to building an almost human-like robot. However, we will never be able to build a completely human-like robot since robots will never be able to biologically reproduce.

Other than this, theoretically, robots could look, act, think, and feel like humans in every way. There are only technical problems that need to be overcome in achieving this. Such technical problems are being overcome one by one.
