Blade Runner

This was the sci-fi movie we watched and discussed on the Human Robot relationships depicted in the movie.

One interesting line of discussion we had was, what would we define as Robot, specially when robots starts looking Human? if they are bio-engineered to have blood and muscle like us (clones) Vs mechanical: wired and electronic how does the ethics debate change? Are they still Robots?

Second interesting theme was, what is the need to know who is human and who is robot?
Is it the intrinsic human tendency to categorize everything and apply rules based on that? i think in Anthropology this is the phenomenon repeatedly observed where the tribe defines whats self and other, and applies different rituals and rules based on that.
