Are they all really that bad? A few are trying to do good in spite of man.

Notably Colossus, who's mission is to protect man from himself (BTW if you like this story, read the original Colossus and the sequels, Fall of Colossus and Colossus and the Crab by D.F. Jones).

The MCP was also more for running things to help, "I can run things more efficiently than any man...", even if it meant hacking into other systems to do it. I general TRON was more about recovering stolen data.

Of course HAL had bad management instructions that messed with his logic.

Not saying I want to be ruled by computers but I think there's more to the computers' side on some of these...

The most complex timepiece is the sky above, way more moving parts than an hourglass.

Though its not technically a space helmet, I think they should have included this bad boy: http://i86.photobucket.com/albums/k109/mrgrum/things-to-come.jpg

Given it has happened several times and apparently the cat seeks out the keys, I think Milo probably has a purpose in mind and not to take the keys...

I can think of three possibilities, one Lilo likes the sound or bling the keys provide, two, the weight of the keys are comfortable for him, or three, the weight reduces the binding of the collar on the throat. I think the latter could be the case, but I'm not Milo.
