An anarchist discussing how the US is a fascist, fundamentally racist state that starves the poor in favor of the rich, only to to turn into a red, white, and blue patriot the moment someone claims the Civil War about states rights and not slavery.

I hate gay Halloween, what do you mean you're the background characters in a romantasy novel?

Of course women don't like the Cybertruck.

Women only want one thing, and it's the Lunar Worm rover concept Philco proposed for the Apollo program in 1966.

It simply depicts his pushcart, surrounded by the broken thrones of dictators.
The monument to Mohamed Bouazizi, the Tunisian vegetable seller who's self-immolation in response to endemic government corruption ignited the Arab Spring. It is a simple sculpture in white stone, depicting a wheelbarrow-shaped pushcart, resembling the one Bouazizi used to peddle his produce, surrounded by the broken thrones of dictators. On the plinth on which it stands, a graffiti artist has written in red spray paint, "For those who yearn to be free"

Every once in a while when I'm feeling down about my lack of career opportunities, I think of the actual cover letter I sent when applying to an 'AI Alignment Data Scientist' position (i.e., someone who's job it was to make sure the superintelligent AI is good instead of evil), & I feel a bit better
Dear Hiring Manager, I’m applying for your open position of Alignment Data Scientist. From the information posted, it’s clear you want someone who’s enthusiastic about the use of AI/ML in tech, immersed in cutting-edge research, and who cares deeply about the problem of ensuring AI alignment in the context of a potential take-off scenario. I am not that person. I honestly hold your whole industry in contempt, and consider it at best a harmless collective delusion that you’ll be able to create a machine god who will fix all your problems, and at worst a socially and environmentally destructive scam. But you should still hire me anyway, and here’s why: First off, due to my extensive background in complex systems science and advanced degrees, you can trot me out in front of potential clients and I will spout off lots of fancy-sounding phrases about emergent complexity, scale-free graph topology, and basins of attraction in the context of chaotic systems. This will impress them, and they will give you lots of money (a portion of which will then be given to me). Secondly, on the off-chance you do manage to produce an AGI, you’ll have someone who it will likely be willing to communicate with, as I am a pleasant person who’s interesting to talk to, whereas most TESCREAL-aligned AI-centric businesses are typically made up of some of the most insufferable people on Earth. I’d honestly rather be doing astrobiology, and answering real fundamental questions about life and the universe, but since your comrades at DOGE took an axe to NASA science funding, hiring me is the least you can do to make up for it. Sincerely, Dr. Theresa Fisher

Arizona is the only place I've ever lived where your car can be *dirtier* after a rainstorm. I can only assume it's because of all the dust in the air?

Assuming this is real and something they can pull off, what bothers me most at this point isn't even the genocidal implications of declaring an entire marginalized population mentally unstable, it's how fucking pathetically cringe they're being about it

Got to see award-winning, best-selling author buckaroo @chucktingle.bsky.social last night at the Mesa Arts Center, and even got to be part of his on-stage magic trick
Buckaroo Chuck Tingle, in his signature pink bag face mask, silver jacket, and silver shorts, on stage standing in front of a projected slide that reads "WORLD'S GREATEST BOOK TOUR" Chuck on stage with four buckaroos (including Tessa!) selected from the audience to participate in the magic trick Chuck, mic in hand, standing on stage in front of a projected slide that reads "The next time you think, 'This doesn't matter so I'm not going to do it', try, 'This doesn't matter, so I might as well go for it'" Tessa, in a long, gold-and-white floral pattern dress and holding her ace of diamonds card from the magic trick, poses next to Chuck Tingle who is giving a thumbs-up

Found out today that by using millisecond pulsars as your reference points, you can determine your position in the galaxy down to 7km or less, which is frankly a ridiculous degree of accuracy on the cosmic scale #PSETI2025

A very sleepy Sophia, wondering what on Earth I'm doing up at 3:30 AM. To be fair, I was wondering that, too.

Allergies are absolutely killing me today (though, weirdly, only my right side?). Took a claritin two hours ago and it's helped, but not by much
