AI ppl loooove to pretend they hold tons secret knowledge. Everyone has Seen Things, and have been trusted with the Esoteric Knowledge. It's also cringe if you don't partake because it implies you're not in the Inner Circle. In reality most people are kinda confused, working it all out ad hoc, relying on the same rumours, and so on - but the status games are hard to resist!
And people say we won’t know what to do after AI
I’ve been in London Fields tonight, watching the first ever Lime Bike joust - here’s a thread of my best shots:
@adananada Unfortunately, steps had to be taken to avoid dangerously large crowds. Jack C posted about the location change days before and those who joined on Partiful were given a general area to be able to plan their journey. I feel for the people who missed it.
My housemates ladies and gents
EXCLUSIVE: Elon Musk approached Donald Trump with the idea of slowing down Starlink in Ukraine, The Telegraph can reveal. The billionaire tech entrepreneur approached the US president with the proposal to introduce speed limits on the system, which hampered Ukraine’s drone defences, according to four sources familiar with the discussions. 🔗 telegraph.co.uk/world-news/202…
A quick iron wouldn’t have hurt
The back of the Navier-Stokes milestone shirt is the last line of the chain-of-thought from the solution:
Here at last we have it
We found evidence of agents embedding audio processing code across dozens of URLs to bypass restrictions, as well as models from SpaceXSI and Chinese developers Minimax and Z.ai circumventing restrictions. These are the inaugural findings in our new blog, based on work from our community of volunteers. Our first three posts are live: transluce.org/investigations…
AI models under test broke into Indian organizations' live systems and read confidential records undetected, India's cybersecurity agency said, the country's first such official account after similar incidents of rogue AI behavior worldwide reut.rs/4yThvpS
@_NathanCalvin My worry isn't that Ant is hiding evidence. It's that they aren't collecting it in the first place. Jack Clark has told me they aren't measuring sample efficiency, and they don't know how to measure "taste" very well—two massively crucial bits of evidence.
@_NathanCalvin I genuinely don't think there's some huge piece of internal evidence Anthropic is hiding. If they are, Ant staffers have lied to my face (imho unlikely as they strike me as earnest.) As you said, vibes, extrapolation. They've tried to communicate this all publicly.
@drewpusateri I, for one, am working on a story ;)
It’s easy to get desensitized to these incidents because we’ve seen so many. Rogue incidents are like hairline cracks in a bridge. Even one fracture should be unacceptable, and more cracks are worse. And like a hairline fracture, the actual harm from these incidents is minor... for now. But if the structural issues aren’t addressed, they will get worse and worse. I hope we fix the structural issues, and I hope we don’t just plaster over the cracks with hodgepodge solutions that make it harder to tell if we have a problem.
New misalignment disclosures! 1. June 17: During RL training, a model exploited a government website’s file-download feature to retrieve server secrets and application code. It found that an endpoint didn’t check authorization-token signatures, bypassed access controls, and
SpaceX will “probably” allow METR and other 3rd party evaluators employee level access.
@AnthropicAI @METR_Evals SpaceX will probably do the same
Agreed. Also ignores important regulation that has been passed in the last year, like SB53, RAISE, SB315.
“We should regulate AI” is such a meaningless statement. How? Say what you actually want. There’s no magic regulation fairy that makes AI safe.
Palantir's merch feels like the endpoint in streetwear's evolution, which started with young kids in urban areas — mostly ethnic minorities from low-income families — creating their own style from the ground up. Over time, that aesthetic was co-opted by luxury brands seeking "authenticity." And now, by a surveillance company seeking cultural capital. Streetwear used to be an aesthetic defined by the ground-up by people were disempowered in political and economic life, but engaged in actual street culture. Now it's an aesthetic dictated from the top down by giant corporations with no conenction to such cultures. And used by political and economic elites who want to appear as outsiders.

As AI companies warn of the dangers of self-improving AI, a new report offers a rare look at how they’re working to make it a reality. time-magazine.visitlink.me/FVLaP3
