I am far from the first person to point it out, but I think I will not be tuning in for a discussion of God sponsored by a bank.

Sometimes I see people like 20 tweets deep into an argument with Grok. Like, what are you doing brother? You are trying to win an argument with a vending machine.

ICE arrested comedian Robby Roadsteamer for singing a parody of Rod Stewart’s β€œDo Ya Think I’m Sexy” in a Jeffrey Epstein the Giraffe costume outside their facility.

He sings β€œIf you hate brown people / and you are a Nazi” and ICE thugs grab him and drag him into detention. No violenceβ€”just speech.

This Supreme Court will do anything it can to ensure the end of our representative democracy.

This is a naked effort to save a racist, nihilistic, principle-free far-right minoritarian movement from disappearing from American politics by instead giving it hegemony over the United States... forever.

@washingtonpost.com - I have resisted the urge to drop my subscription, arguing that we need to support investigative journalism or it won't exist anymore. Your firing of @karenattiah.bsky.social is the last straw. I cancelled today. The WaPo that helped preserve democracy in the 1970's is dead.

"Harvard can't use race as a factor in admissions, but ICE can use race as a factor in detentions" is a retrenchment essentially to a pre-Civil War understanding of the Constitution. It's vanishingly few steps removed from "Latinos have no rights which the white man is bound to respect."

The reason I cannot use "AI" in my writing is because I am not speaking merely to be heard to speak.

I am speaking because *I have something to say.*

The things I have to say could not be said by anyone else because these words are mine.

If you don't understand that, I genuinely can't help you.

β€œSlight changes to wording that correspond to large changes in meaning” β€” this, of course, comes from the token embedding which creates a β€œsemantic space”, but one which is not necessarily the same as the semantic space that humans learn in early childhood development.

Skills, in general, are "use it or lose it" -- at least, if you don't use them, you'll suffer some erosion in your level of performance. I've been saying this for years with mobile mapping and traffic apps -- navigation skills and mental maps are use-it-or-lose-it.

Agreed. This is a useful article on LLM hallucinations. Table 3 in particular on root causes is something that everyone working with these models (at the technical level) should look at.

One of the most important AI papers of the year so far. Basically, part of the structure of the internal representation is transmitted to β€œchild” models simply in question output. Fascinating, but highly problematic since it means curing bias is probably no easier among LLMs it is in humans.

Avi Loeb has been seeing β€œalien craft” in the sky since β€˜Oumuamua. In 2023, he β€œdetected” an alien ship, but another team demonstrated that he mistook ordinary truck traffic for evidence of the meteor. He’s better at publicity than science these days.

Good paper with a new benchmark on LLMs and tax prep -- they're not ready for this kind of reasoning yet. Even on simplified sample tests, SOTA models got it right less than a third of the time.

Spreadsheets, calculators, and accountants are still your friends.

Apparently, it's been difficult to get Grok to be right-wing enough, just training it on actual knowledge and books and the contents of the Internet.

This is why we need to support the Wikimedia Foundation and other open sources of information and knowledge, more than ever.

Remarkable.

MSNC: "I want to reiterate this has been 100% peaceful."

Seconds later, LA County sheriffs start firing on the crowd.

Yet again, "law enforcement" deliberately escalated.

As Cervical Cancer Deaths Plummet, Experts Credit HPV Vaccine HPV can cause a variety of cancers, including cervical. New mortality data for women under 25 point to the success of the HPV vaccine.

A recent study found that cervical cancer deaths in young women have plummeted since the introduction of the human papillomavirus vaccine.
