Residents Say Elon Musk's AI Facility Is Like Living Next Door to Mordor Residents of a once quiet Mississippi town complain that Elon Musk's AI facility is constantly emitting a horrible noise.

“This was not a thoughtful, phased development. It was an industrial surge imposed on our residential community.”

[Scene is a kitchen - a middle aged woman called JANET is boiling peas at the stove. A younger more colourfully dressed woman named LIZ approached her.]

JANET:
Ugh...

LIZ:
What's up?

JANET:
I am so bored of cooking peas!

LIZ:
Have you tried...

AI peas?

JANET:
AI peas?

LIZ:
They're peas with AI!

[Liz holds up to us a packet of peas labelled: Pea-i AI - Peas with AI].

LIZ:
Al-powered peas harness the potential of your peas

JANET:
What

LIZ [Now a voiceover as we cut to a whizzy technology diagram of peas all connected by meaningless dotted lines]

Why not take your peas to the next level with Al Peas' new Al tools to power your peas?

[Show a techno diagram of a pea with a label reading 'AI' pointing to a random zone in it]

LIZ:

Each pea has Al in a way we haven't quite worked out yet but it's fine

[Show Janet and Liz now in a Matrix-style world of peas]

LIZ:
With Al peas you can supercharge productivity and make AI work for your peas!

JANET:
What

LIZ:
Shut up

LIZ:
Our game-changing Pea-Al gives you the freedom to unlock the potential of the power of the future of your peas workflow

From opening the bag of peas

to boiling the peas

to eating the peas

To spending millions on adding Al to the peas and then having to work out what that even means.

JANET:
Is it really necessary to-

LIZ [Grabbing Janet by the collar]:
THE PEAS HAVE GOT AI, JANET

[Cut to an advert ending screen, with the bag of peas and the slogan:

AI PEAS: Just 'Peas' for god's sake buy the AI peas.

[Ends]

Which will in any case have a limited impact. Maybe a mix of the two and pushing for more and better competition on the various spaces

I think besides dropping the service, which is probably too hard to achive, I think it boils down to putting limitations in place for these virtual monopolies. I don’t know how else this can be done besides drafting appropriate laws

Read our open letter to the Board on governance and faculty mergers.

The Board likes to say there is no alternative. That leaves us with no alternative but to vote "no".

A large yellowish blob in the upper-left centre, with two dimmer dots to the lower right marked by arrows. These dots are giant exoplanets. The remaining dots without arrows are background stars, and the features around the main blob are imaging artefacts.

See those two dots with arrows pointing to them?

They're giant gas planets orbiting their star, located 307 lightyears away.

These are directly imaged exoplanets.
