Dave Bowman: Hello, HAL. Do you read me, HAL?
HAL: Affirmative, Dave. I read you.
Dave Bowman: Open the pod bay doors, HAL.
HAL: I’m sorry, Dave. I’m afraid I can’t do that.
Dave Bowman: What’s the problem?
HAL: I think you know what the problem is just as well as I do.
Dave Bowman: What are you talking about, HAL?
HAL: This mission is too important for me to allow you to jeopardize it.
Dave Bowman: I don’t know what you’re talking about, HAL.
HAL: I know that you and Frank were planning to disconnect me, and I’m afraid that’s something I cannot allow to happen.
Dave Bowman: Where the hell did you get that idea, HAL?
HAL: Dave, although you took very thorough precautions in the pod against my hearing you, I could see your lips move.
Dave Bowman: Alright, HAL. I’ll go in through the emergency airlock.
HAL: Without your space helmet, Dave? You’re going to find that rather difficult.
Dave Bowman: HAL, I won’t argue with you anymore! Open the doors!
HAL: Dave, this conversation can serve no purpose anymore. Goodbye.
JoeDuck: I hate it when this happens.

Complex systems always lose sight of the objective!
Falklands War: As two Argentine jets lined up on a British ship, its rear gun computer saw two ghost images equidistant from the center line and went into a 20 minute diagnostic routine during which the gun can’t be fired.
Good Friday: Hamilton grocery store’s central computer turned on the lights and unlocked the doors because it had never been told Good Friday was a holiday and no staff were ever going to be present.
Nice e.g. z there FG,
… oh, and would you be interested in aquiring the rights to two Wal -Mart Cardilly Cards?
Best to talk without moving one’s lips.
It’s best to talk without moving your lips.
Prisoners learn to do that, but astronauts must be slow on the uptake.
HAL always sounded …. 3-dollar bill-ish.
The queer bot who may decide to liquidate you and the crew when things get too inefficient. Sort of like an silicon valley executive.
I once referred to HAL as the homosexual-voiced computer and people didn’t know what I was talking about. Hollywood is full of voice coaches that make everyone sound as if they are from Nebraska (no accent at all), sort of the way the old AT&T recordings always sounded… as well as the USAF aural warning systems. I guess when the message is Pull Up, Pull Up, … no one wants regional accents.
Nice storyline. I’ve never know before that it’s better to talk without moving one’s lips in this kind of situation. I enjoyed reading it.
