We’re at the second anniversary of ex–Google engineer Blake Lemoine’s widely ridiculed claims that large language models are sentient. I’ve spent hours talking to him and, yeah, he does say some cringey things. But he also gave me much to think about. www.criticalopalescence.com/p/is-blake-l... 🧪

Scientists find 17th-century shipwrecks that are filled with rat skeletons. I guess the onboard menu was rat cake, rat sorbet, and rat pudding. You just gotta love @parshallison.bsky.social’s story of how brown rats edged out black rats (which taxonomists have creatively named Rattus rattus). 🧪

Has anyone else had trouble with the NYC Subway fare payment system, OMNY? I got an email saying my card was declined, but the bank says there is no problem, and OMNY gives the same error with a second card. I'm locked out of the subway until they fix this!

Download a fully functional version of GPT-2 as an Excel spreadsheet and see how it does its thing. The author posts tutorial videos at www.youtube.com/@Spreadsheet.... You can see how word embeddings encode meaning as well as the word associations made by the network’s self-attention mechanism. 🧪

"Of more than 200 people undergoing surgery... nearly 60% had microplastics or even smaller nanoplastics in a main artery. Those who did were 4.5 times more likely to experience a heart attack, a stroke or death in the [next] approximately 34 months." Scary article by @maxkozlov.bsky.social. 🧪

So @kevinroose.bsky.social kind of misses Sydney. I’ve heard others complain about overguardrailing, too. A.I. researcher William Hahn at Florida Atlantic Univ uses jailbreaks to elicit more creative responses: “It will answer scientific questions, I would say, better.… I WANT it to speculate.” 🧪

Erik Hoel’s latest blog post describes a replicability crisis in neuroscience, going beyond the well-known replication issues in psychology. Sample sizes are small, brain “areas” may be an artifact, and researchers are floundering for lack of a generally accepted theory of consciousness. 🧪

People tend to exhibit an ‘overblown implications effect’—overestimating how much observers will take success or failure at a task will be seen as indicative of a wider skill or even a distinct, parallel skill, research suggests:

Can self-reported behavioural survey data be trusted? Research into routine behaviours finds anchoring can distort the outcome, → surveys are not a reliable means of gathering such information. Routine behaviour should be observed in its natural context: buff.ly/3O7fzTu

Wait, do iPhone users really care whether a message bubble is blue or green, or is this just something that @brianx.bsky.social and the NYT have made up? Because, if it’s true, there really is no hope for humanity and we should long for an A.I. takeover.

One of the many many puzzles of this whole OpenAI episode is that people there still use Twitter/X to make announcements, even though Sam Altman, of all people, should want to have nothing to do with Elon Musk. What explains this enduring attachment to Twitter?

Utilitarianism as a decision procedure will tend to amplify risk if multiple people have the power to inflict risk on others, since we will then all be hostage to the person who is most optimistic about the outcome of the risky decision.

Here are a few thoughts on the hard problem of consciousness. Scientific explanation works by relating one thing to another, so it seems unable to describe the intrinsic (=nonrelational) qualities of experience. But with reflection, could we find that those qualities are actually relational? 🧪
