The Second Renaissance Part I

Ever wonder exactly HOW the machines managed to seize the planet and enslave the human race? This Animatrix short details how humans created robots to do their worst jobs for them. Basically it's a metaphor for a third-world divide. But when a single robot rebels political opinion of the machines turns sour and they are banished to their city, where their economy thrives, turning the human world into the new third-world. Oh, the irony.

It's a fascinating short and really makes you think if whether or not the soul is purely a biological thing, or if a sentient robot can earn one too, kinda like Bicentennial Man.
