A while ago I got the one with Smiffy laughing... slightly disturbing to say the least.
Anyway, I was enjoying that thread we had a while back with all Ashrak's theories, so I'm reviving its spirit and trapping it in the shell of this one. Now, we had concluded that the reason the Matrix was inherently unstable was because of the machines inability to think outside the box, that is to say they think in ones and zeroes whereas humans can hold two opposing points of view at the same time and believe them both to be right, and go on to make illogical actions because we can choose our own fate, choose to fly in the face of all logic if we wish.
Now, the moral of the Matrix trilogy is all about the human ability to make choices. Which is why Neo was able to save Morpheus - the machines never expected a rescue attempt because the chances of sucess were so low that they would never have made the attempt themselves. Their logic dictated that Morpheus would be killed. But Neo made the choice to go, despite reasons not to. Hence the lines 'nothing like this has ever been done before' 'I know... that's why it's going to work'. The machines simply couldn't conceive a human making such a foolhardy attempt.
Anyway, what I believe will be the great irony of the overall story is that while choice is what seperates us from them, it will not be our choices which defeat the machines in the end. Because in a story of so many variable, with so many twists and head-****s, where nothing is ever as it seems, the real wild card is Smith. And Smith is now free from the system (well, so it appears). Morpheus line 'he fights for us...' in Revolutions has me convinced - it is Smith's choice that will defeat the machines. Not, perhaps, because he likes us but because he hates them for imprisoning him for so long in the Matrix amongst the smelly organic beings.
My money's on Smith to be the deciding factor. Roll on November! (or whenever it's out)
