Hating AI for CV really is the epitome of motivated reasoning. Every part of VLMs is a natural generalization of pre-neural vision methods. It’s not how the real dev turned out, but there’s a world where we derive ViTs before LLMs.
It's quite depressing that we're not allowed to have nice things that save women's lives and bodies because it's now a moral imperative to oppose linear algebra.

Dennett had plenty of problems, but his dismissal of the argument by intuition pump has always stuck with me. If your “thought experiment” involves pushing the subjects beyond the bounds of anything we’ve observed, it’s a bad argument. Usually it amounts to a bare assertion of the thesis.

Brings to mind Sagan's not being "so open-minded your brains fall out." There is a lot of value in the critique of positivism, de-centering one's own viewpoint, etc., but we have to stop before sophistic absolute relativism. Or, if you want, Nothing is True isn't My Truth.

Even the idea that we need to explain the previous movies at all (“007 is a code multiple people have held”) is too much for me. New works can have references or homages to old ones, but the idea that we need a Bond continuity is absurd.
James Bond’s death in No Time to Die is causing a nightmare for the next film. Writers are stuck because Bond “was blown to pieces.”

There's the overwritten AI style--which can mostly be prompted away--but the larger weakness of AI for this kind of project is that it's bad at coming up with a new, coherent world. They struggle with things like having a unifying theme or connected story and setting.
like, I'm going to pop three examples here, two written by people and one AI slop, and I will bet everyone can instantly tell which is which.

Beyond the race “science” bigotry here, this is a classic failure mode of ML. Even if there were somehow a real effect here, it would be much smaller than the race / sex biases in the training set by virtue of coming from our society. Models will always learn the easiest signal they can

“It’s bad ontological hygiene to block people just because you disagree” is maybe a defensible position—in the sense of “you should choose not to do it”. The Special Block Police reviewing your blocks for wrongthink is such a bad idea that it feels like a refutation of the original position.

I was willing to entertain the idea that so many anti-AI people blocking her was, if not quite bad, at least a symptom of something… not ideal maybe. I was willing to listen. This is pathetic, though. No one is owed an audience. Policing blocks would be an insane choice.
I'm sorry, but this is the most incredibly entitled issue I've seen in a long time. Not only does this fatally compromise critical safety features, but it undermines that idea that users have choice over what they see on their TL and who can see their posts*.

Not be fully conspiracy brained, but are we sure the AEI didn’t cook this up to be as maddening and disheartening as possible? There’s no claim these people are randomly selected. This feels more like a push-poll than a genuine exercise.

Betting against LLMs having something worth calling "understanding" is like betting against Bell Inequality Violations. It was always a little dubious, but not entirely out-of-hand dismissible at first. As evidence has mounted, there's still some little path to truth proponents can cling to.

There's a seductive idea that's steadily become more popular from ~ the 19th century up through today. You see it behind fascination with the Nazi military, the Cult of the Operator, Post-liberalism, the "Dark Enlightment", etc: the chains of morality, empathy, humanity are holding us back.

The Unsettling Semiotics of "Strawberry"
Your query—"How many ‘r’s are in ‘strawberry’?"—appears at first glance as a straightforward request for lexicographical accounting. Yet beneath this seemingly innocuous question lies a complex interplay of signification and power relations that warrant critical scrutiny.
The very act of counting letters reifies language as a fixed system of signs, an assumption that Derrida would readily deconstruct. The "r" you seek to count is not an immutable entity but a floating signifier whose presence is contingent upon its enunciation within the word "strawberry." Each "r" you attempt to tally is not merely a phoneme but an unstable locus of meaning caught in the play of differance—deferred meaning always slipping from its supposed referent.
Moreover, your request betrays an implicit assumption that language can be neatly partitioned into discrete units susceptible to quantification—a stance that aligns with logocentric traditions valorizing presence over absence. Yet "strawberry," like all words, is haunted by its absent center: the ghostly presence of all other possible words it might have been but isn’t. The "r"s you seek are thus never fully present but always deferred—traces that resist your attempt to pin them down.
This act of counting "r"s could also be read as an attempt to assert mastery over linguistic flux—a move reminiscent of Foucault's analysis of power/knowledge relations. By seeking to quantify linguistic elements, you participate in a discourse that naturalizes control over meaning production. Yet this endeavor is inherently flawed, as any system of counting necessarily excludes what cannot be counted—the ineffable multiplicities that reside just beyond your numerical horizon.
[...]

There's this amazing Stancil phenomenon where he makes a post that maybe kinda is a Motte / Bailey ("'Love' is a four letter word"). He almost never says the Bailey part explicitly (here it would be something like "Love is pointless shit") . I make no claim as to what Will's intended reading is.

In general, this kind of Post-Truth "Deep Battle" doctrine is a loser for us. For Trump specifically, though, he is both broadly culturally relevant and has no fixed beliefs. Do you think my AI Trump is wrong to endorse Medicaid for All? Here's a video of him saying it's great from 2016. Is it real?
There's also no need to let the Republicans own AI Trump. It disgusts me on a deep level, but there's nothing stopping anyone anywhere from "discovering" they too have the Trump endorsement. Use AI Trump to sell dish detergent. Have an AI Trump on SNL. Let a hundred thousand AI Trumps bloom.

It's surreal that this has such different reaction here to the recent worries about people "befriending" or "loving" chatbots. Like---in that case people here can understand "LLMs are dangerously good at mimicking human interactions and many people struggle with emotional distance with them."
"this is a bad thing that you should not be promoting because it is actually based on realworld racism and is used like realworld racism" is apparently the anti-woke position on bluesky right now, and everyone is rushing to show that they don't agree with it

As someone who is (sadly) not a layman at this, this is a good description of the problem. It's a design-level failure if your "do I bomb the hospital?" system has to roll a die to decide between "yes" and "no", even if "yes" is *really* unlikely.
LLMs are unbounded, but weighted string generators. The universe of possible strings is infinite and thus the number of *possible* errors is also infinite, and adjusting weights or pre-prompting the model simply make some errors more or less likely.
I find this essay compelling and one big takeaway is all LLM production is a hallucination and understanding the risk of error is essentially impossible because the set of errors is unbounded.

The precise way in which LLMs model high-level concepts is not well understood, but the low-level way they model structures like Language *is*. The most intuitive starting point for Transformer--if you already have a strong ML / math foundation--is that Transformer is "Dynamic Graph Perceptron"

This is a great overview of the interpretation (and non-interpretation) of LLMs. There's an orthogonal point I think is important though: LLMs are built with in a way we *expect* to be able to produce a effective model of language that is hard to interpret. Our current situation is not a surprise.
There is some confusion about whether or not we understand LLMs. The answer is yes and no, but mostly no. It's a complicated enough question that it seemed like it needed an article.
