This might strike some readers as harsh, but if you’re excited about AI, there ain’t no way we can be friends.

None of this is making the slightest dent.

She seems otherwise intelligent. She is widely published in mainstream publications. She has written books that sold well.

She absolutely refuses to entertain the possibility that a ChatGPT answer is not sufficient proof that a fact or statistic is true.

One of the most miserable things about living in this era is having to watch the stupidest & most arrogant people in the world have to relearn The Why of literally everything good that we collectively do the hard way.

The answer is always ‘Because a bunch of people died, fuckwit.’

Sorry to be Radical Left but I don't think we should put people who haven't committed a crime, and aren't even accused of committing a crime, into any sort of "Detention"

Me after finishing season 2 of The Night Manager:

TW: Self-harm

It’s generally difficult/impossible to assign blame after a suicide; because sometimes, even the ideal therapist or friend can’t prevent a single moment of desperation.

HOWEVER it should be incredibly easy to argue before the law that ChatGPT has ended lives by encouraging suicide.
Immediately after I posted this I was like …in addition to all the people this kind of AI has ALREADY KILLED and you know what, maybe technology that provably gets people killed should not be legal
jfc people are going to goddamn die because of this thing if they aren’t already

Sorry you lost your healthcare; we need to build more concentration camps.
In the last month ICE has bought warehouses in:

- Hagerstown, MD: $102 million
- Surprise, AZ: $70 million
- Hamburg, PA: $87 million
- Tremont, PA: $120 million
- San Antonio, TX: $82 million
- El Paso, TX: $123 million
- Social Circle, GA: price unknown

This is unprecedented.

If you only read one post today, make it this one:
I'm convinced AI is our generation's radium - a discovery with genuinely useful applications in specific, controlled circumstances that we stupidly put in everything from kid's toys to toothpaste until we realised the harm far too late where future generations will ask if we were out of our minds.

Never thought about this before, but it’s 100% what makes the Muppet Show special
the magic of the Muppets is that there are two fourth walls. they constantly break the one that reminds the audience they are performers. they NEVER break the one that reminds the audience they are puppets. this dynamic is the key to their entire comedy style
MY KIDS: so why are there muppets in the AUDIENCE

ME: THE CONCEIT!! IS THAT THEY'RE PUTTING ON A VARIETY SHOW!!! IN A WORLD WHERE MUPPET AND HUMAN COEXIST!!! YOU ARE WATCHING A DOCUMENTARY!! FILMED!! IN REAL TIME!!!

What a fascinating musical piece without any current-day political connotations at all. Just plain good historical jazz music by Lizzy & The Triggermen (they’re not on Bsky but go find them on Insta)

“When I was out at sea, I saw a young lady sitting on a rock, and she told me in a singing voice that the function of prayer was not to influence God, but rather to change the nature of the one who prays.”

1859 was a momentous year:
The Comstock Lode discovered in Nevada.
Edwin Drake drilled 1st US oil well in Titusville, PA.
The Suez Canal begins construction.
Darwin's "Origin of Species" was published.

And the Sun exploded.

Let's talk about the Carrington Event of 1–2 September 1859.
Auroras likely as most active sunspot in years turns toward Earth
The sunspot region 4366 fired off dozens of powerful solar flares in 24 hours, including the single strongest flare since 2024. Auroras are possible later this week.

Is there a urologist around? I want to ask a question about something I am writing.

There’s absolutely zero reason to assume this, but in my mind, Sturgill Simpson‘s “Sing Along” and Ashnikko’s “Skin Cleared” are about the same couple breaking up.

Sorry to plug German-language stuff, I swear I’ll stop, but I need y’all to know that our Nerds at Work Podcast is now also available on my colleague @christianscharun.de‘s YouTube channel (audio only). And it’s good timing too, because our current episode is pretty unique:
