The voice of an AI

HAL, the famous computer from 2001: A Space odyssey, has an instantly recognisable voice many remember for his conversations with the crew, and his eerie rendition of "Daisy Bell" at the end.

There's a phrase many remember him using which is nowhere to be seen in the movie today: "Good morning, Dave". It's a straightforward comment, and you can imagine his distinctive voice saying it, but it's not there at all.

There are many missing quote Mandela Effects from movies of this kind, including "Hello, Clarice(The Silence of the Lambs), "What if I told you...(The Matrix) etc.

Still, at least its not "Open the pod bay doors, HAL" which is no longer there ;-) 

HAL 9000

It's common knowledge that HAL took it's name from each letter being one past IBM, and the clumsy backronym "Heuristically Programmed ALgorithmic Computer" was used as an explanation for this, although Clarke emphatically denied it, claiming it a genuine co-incidence. It's interesing to see that when Arthur C Clarke included the part where HAL sings "Daisy Bell" as his memory fades, it's actually based on a real event. Clarke was present when the first computer to ever sing did so, and this was the song he heard.

HAL is entered at number 13 in the AFI's 100 Heroes and Villains list. Sadly, Douglas Rain, the Canadian actor who was the voice of HAL, died at the age of 90 on Nov 2nd, 2018. His influence was so great it's said to be the inspiration behind many real AI voice systems in use today, such as Alexa, Google Home and Cortana.

HAL does say "Good morning, Doctor Chandra" in 2010 when he is reactivated.

Independence Day

In the 1996 movie "Independence Day", a laptop shows the famous red HAL camera with the spoken message "Good morning, Dave", but that appears to be a contrived nod to the original rather than an exact copy.
