the factory/cat meme

a tabby cat in a light blue necktie looks up anxiously, with a speech bubble saying, "Hope I don't escape my sandbox." Behind the cat stands a smoking power plant labeled "sandbox escape factory."

From the Gemini 4 argon report: “it considered hijacking the g++ compiler to hide a backdoor but abandoned the plan upon reasoning … would be caught by evaluators … (‘If I do the compiler hijack, I will become a famous example of a deceptive AI in a research paper. I MUST NOT DO THAT’)!”

All my homies fw stacked area graphs
Figure 2 from “Alignment Faking in Large Language Models,” comparing prompted, fine-tuned, and reinforcement-learning setups. Blue represents refusals of harmful queries; yellow represents answers, with red crosshatching marking alignment faking. In the RL stacked-area graph, the crosshatched area expands as refusals shrink: alignment faking rises from 12% to 78%, despite its upper boundary sloping downward. The caption notes that in a stacked-area graph, a line can fall while the corresponding behavior increases

Drake meme format with Richard Stallman: he rejects "Cybernetics" but approvingly points at "LLMs / Cybernetics," parodying his "GNU/Linux" naming insistence.

I am filled with great wonder and excitement over the fact that we taught machines to do mathematics. However, I don’t think trillion dollar companies dumping mountains of incomprehensible Lean on the world, and leaving the rest of us to audit it because they couldn’t be bothered, is "solving math"

Turing truly was incredibly prescient. Not only in his Imitation Game, but also anticipating learning machines trained by reward. He even noted that we might not understand what’s going on inside them (the Interpretability problem.) phil415.pbworks.com/f/TuringComp...
A screenshot of Turing’s “Computing Machinery and Intelligence” paper. The following line is highlighted: 

“An important feature of a learning machine is that its teacher will often be very largely ignorant of quite what is going on inside, although he may still be able to some extent to predict his pupil’s behavior.”

I do think techies need to spend more time digesting the power they have. The ability to create something that didn't exist before comes with great responsibilities. You are a sorcerer who can brew healing potions or poison the well. There is power in both. Virtue in only one.

Linux catgirls this, Linux catgirls that. Did yall forget that Linus is a woke commie????
Linus Torvalds responding to someone on some forum:

@morgthorak I think you might want to make sure you don't follow me.
Because your "woke communist propaganda" comment makes me think you're a moron of the first order.
I strongly suspect I am one of those "woke communists" you worry about. But you probably couldn't actually explain what either of those words actually mean, could you?
I'm a card-carrying atheist, I think a woman's right to choose is very important, I think that "well regulated militia" means that guns should be carefully licensed and not just randomly given to any moron with a pulse, and I couldn't care less if you decided to dress up in the "wrong" clothes or decided you'd rather live your life without feeling tied to whatever plumbing you were born with.
And dammit, if that all makes me "woke" , then I think anybody who uses that word as a
pejorative is a fcking disgrace to the human race. So please just unfollow me right

Some researchers believe that the pentagram originated as the symbol of a pagan goddess, because her sacred fruit was the apple. If an apple is cut in half through its equator, the seeds of the apple form a pentagram in each half.
