Your support helps us to tell the story

From reproductive rights to climate change to Big Tech, The Independent is on the ground when the story is developing. Whether it's investigating the financials of Elon Musk's pro-Trump PAC or producing our latest documentary, 'The A Word', which shines a light on the American women fighting for reproductive rights, we know how important it is to parse out the facts from the messaging.

At such a critical moment in US history, we need reporters on the ground. Your donation allows us to keep sending journalists to speak to both sides of the story.

The Independent is trusted by Americans across the entire political spectrum. And unlike many other quality news outlets, we choose not to lock Americans out of our reporting and analysis with paywalls. We believe quality journalism should be available to everyone, paid for by those who can afford it.

Your support makes all the difference.

Sir: I have just read the article "Arthur C Clarke's brainchild" (Network, 13 January). Sunday, 12 January is claimed to be the day that HAL, the intelligent computer, "became operational" in the film/book 2001, A Space Odyssey.

I have watched the film again. About 1 hour 40 minutes into the film, while his higher functions are being cut, HAL is heard to say: "Good afternoon, gentlemen. I am a HAL 9000 computer. I became operational at the HAL plant in Urbana, Illinois, on 12 January 1992" - not 1997.

The story underwent numerous rewrites, and the plot varies between the film and the book. Small wonder HAL became psychotic - the first uncertainty it had to deal with was its age.
