Tallinn, who led Anthropic's series A, funds METR, the "auditing institute" people took seriously 🙄 After criticism that METR was laughably NOT independent, Anthropic announces they'll pay Accenture to "audit" Accenture had acquired Tallinn firm which will be doing the "auditing" Full circle 🙄

just read a post on linkedin; AI generated and about their son's medical issue, relating it back to business. i'm happy the kid's alright but have complicated feelings about using the kid's medical journey as content particularly when they couldn't be bothered to write it their self?

I've been reading High Output Management by Andy Grove and while it's a classic for a reason it feels very relevant today while also providing a lot of historical context, even for its time, which I appreciate.

Astrophotographer Adam (AJ) Smadi caught this image a few hours ago from Washington state. A thin crescent Moon, sunlight illuminating the rugged lunar surface. And 2,400 times farther away—and on the other side of the Sun—mighty Jupiter, and its moons Io (left) and Ganymede (right).
A crescent Moon seen during the day, arcing from upper left to lower right of the frame. At lower centre is the full disk of Jupiter; the small dots to its upper left and lower right and Io and Ganymede, respectively.

🔇 🔇 🔇 My book, Deep Unlearning, is now available for preorders! I don't know how people write so many books because this one took a lot out of me. It turns out, I had a lot to say 😂, with editors cutting out 50k of my words 🫣 ✴️ You can now preorder it at www.simonandschuster.com/books/Deep-U....
Cover of my new book, Deep Unlearning: The Rise of AI and The Radicalization of a Tech Idealist. 

There are two concentric circles in the book, the left being circuits in black an white, and the right being a bunch of dots with orange accents. The cover background is cream. And the words are written in black except for "Un" which is in orange.

Another resistance quilt finished this week. The eye is my own design, the letters are a fpp pattern by QuiltByNight, the rounded corners and black binding are meant to resemble the phones we the people are using to document the horrors and disprove the government’s lies about what they are doing.
A multicolored quilt made of of scraps with the words WE KNOW WHAT WE SAW staggered down it with a large beautiful eye centered between the words. The eye has a rainbow camera aperture as the iris. It is quilted densely.
