The social scene around AI and AI safety is more unpleasant than I realized. I'm sure there are other sides to it. But when you get a lot of men with too much money who think they're saving the world, surrounded by groupies, what do you expect? Read the long Bluesky thread about this, collected on one page: https://skywriter.blue/@segyges.bsky.social/3mvom4b4dn22q I can't confirm this stuff - I stay far away from this scene. And the sentence "AI Safety is Mostly a Sex Cult" is a massive exaggeration. But... (1/n) AI alignment Related

I'm going to come right out and say it: statistical extrapolation is *fine*. One of the most useful ways to understand the present and anticipate the future is to measure the things that happened in the past, find the correlations among them, and extrapolate likely future outcomes from those correlations. - If you'd like an essay-formatted version of this thread to read/share, here's a link to it on pluralistic.net, my surveillance-free, ad-free, tracker-free blog: https://pluralistic.net/2026/09/18/surprise/#wow-signal 1/ Related

Apple design its own chips for its phones. The latest CPU is the A20 Pro. Geekbench is a benchmark with a database of results; you can run your own benchmarks and share your numbers with the world. In the last few days, we finally got some A20 Pro results and the numbers are impressive... reaching 4000 in single-core (one thread) performance. For comparison, the best that you can do with an x64 AMD or Intel processor is something like the Ryzen 9 9950X3D2 at about 3,163 which would be somewhere between the A18 and A19. The A20 Pro is 25% faster on this benchmark than any AMD or Intel processo… benchmarks Related

everyone should go read @dwarkesh_sp’s post - it does a great job of laying out the timeline and what we know ( and don’t know) I do have two issues with it A) the use of anthropomorphic language. These are not civilizations nor do they have desires just like a CPU thread or a bunch of programs don’t. this doesn’t mean we downplay the importance of this moment for cyber - but using human parallels for what I believe is code is dangerous territory. B) IMO it gets the impact of open source models wrong and is unreasonably dismissive for reasons that are not clear. As @ClementDelangue highlights… open source Related

interest rates government
Their words
Early in the final stage of the Big Debt Cycle, the market action reflects this dynamic via interest rates rising led by long-term rates, the currency declining especially relative to gold, and the central government’s treasury department shortening the maturities of its debt offerings because of a shortage of the demand for long-term debt.

This thread helped me understand that the outrage about Anthropic's watermarking is the confluence of a lack of understanding of how LLMs (or any statistical language model) works and general angst at the current economics. Quoting @hern.bsky.social If you use Claude right now, then it doesn’t pick the “best” word for a sentence. It creates a distribution of possible words, assesses the probability of any given word fitting the slot, and randomly picks between them based on that probability. LLMs Anthropic Related

When you break that, when you overthrow the ruler, when you dissolve the republic, when you put in a new thing, it doesn't have that same staying power. And so, it's very common when there's one regime change for there to then be five regime changes rapid-fire over and over.

I’m gonna delete this thread because I think people complaining about airlines on Twitter are pretty lame, including myself! That said, I think the takeaway is that the reason I was upset is precisely because of dashed expectations. If this were American I would have shrugged my shoulders. So I guess that’s a compliment to United, but also a reminder that it’s risky to advertise things (like Starlink) when you can’t yet confidently deliver on them. Anyhow, 28B on Southwest.

Under a name here, the quoted block is what they actually said.
The korrent beneath it is the claim those words support, in
korrents' wording — tap it to see the record, its source, and who
