DisagreeDid you know that HAL was chosen, because it's one letter previous (alphabetically) to IBM? Not a lot of people know that*... I started to appreciate classical music because of 2001...
Back on thread - nice revival btw - in the movie it worked, that was all that was important. If you can suspend belief long enough to allow a character in deep space (close to zero degrees kelvin IIRC) to go from a pod into the ship without a helmet, where the air in his lungs will expand instantly to such a point they'd burst, and his eyeballs would freeze, then removing a few cartridges of memory is a very small effect to accept.
*probably because it may not be true.... but it sounds good.
I can't cite any sources at the moment, but as a writer the topic of survivability in a vacuum fascinates me, and I've done some reading on the subject. From what I gather, it IS possible to survive for a few seconds in space if as a trained astronaut you know what's coming and are lucky enough to have a moment to prepare. A strong person should be able to keep the air in their lungs for up to ten seconds or so. If you blink quickly you should still be able to see, again for only a few seconds before things start to freeze.
Of course, after about ten seconds all bets are off... The Bowman character pushed the limits but in theory it is possible.
