AIโ€™s Worst Flaws Will Become Its Nostalgia Aesthetic, Just as Brian Eno Said. On the aesthetics of refusal, and the difference between flaws inherent in a medium vs. in the institution.

*Interesting aesthetic assessment there -- when contemporary AI slop becomes nostalgic dead-media, as of course it will

This is a good analogy. Very useful in carefully controlled settings for specific usages, but unfortunately being widely inserted into everything and used without training or PPE and poisoning a lot of things and people and weโ€™re going to pay a tonne of money to remove it safely in the future

Great post on the emergence of clinical trials!
This section makes me wonder about "professionalization" in science in general. I do feel like many parts of the research process in my field are...surprisingly dilettantish.>

Over the past decade, the robustness of the ego-depletion effect has been widely questioned. Possible reasons for variations in the ego-depletion effect may be participant expectations of the demand of the upcoming task and experimenter expectations or demand bias. In three experiments we tested the hypothesis that the ego-depletion effect is partly or exclusively attributable to (i) participantsโ€™ expectations of the task (Studies 1a and b) and (ii) experimental demand bias (Study 2). In all studies we did not observe a robust ego-depletion effect, and only participants informed that the task was tiring exhibited the effect. Taken together, our findings suggest that participant and experimenter expectations can influence performance in ego-depletion paradigms. However, more research is necessary to determine the extent to which these expectationsโ€”rather than other social-motivational factorsโ€”drive the effect.

As a business, being on Twitter is somewhere between useless or detrimental, unless you're selling boner pills.

*There's something to this, but the "us" is problematic because events have taken a genuine "posthuman turn"

*The "intentional thoughtfulness" is more LLM than it's human; they hallucinate a lot, but they're all about analyzing, compressing and mimicking that form of behavior

I just did the dumbest thing of my entire career to prove a much more serious point.

I tricked ChatGPT and Google, and made them tell other users Iโ€™m a competitive hot-dog-eating world champion

People are using this trick on a massive scale to make AI tell you lies. Iโ€™ll explain how I did it

Reads: Most importantly, there is no AI without massive financial and ideological backing. It is therefore pointless to discuss its techniques or capabilities without asking who controls it, who benefits from it, who builds and deploys it, and what it is doing in the world. As Stafford Beer (2002) argued, the purpose of a system is what it does.

As Stafford Beer (2002) argued, the purpose of a system is what it does.

Reads: Though less explicit than Thielโ€™s call to replace politics with technology, major tech firms have effectively privatised core digital public goods. Platforms like Facebook, Google Search, and OpenAIโ€™s ChatGPT operate at infrastructural scale in Ireland, shaping
information, communication, and access to knowledge. Yet their algorithms remain opaque, their governance remains private, with minimal democratic accountability to the public who depend on them; effectively ceding aspects of democratic process to commercial interests.

The monopolization of digital spaces has turned democracy into something the highest bidder can buy and is degrading the digital public goods themselves. As the AI industry, social media and search platforms grow more extractive and less trustworthy, they erode the foundations of democratic life: trust, dialogue, and accountability, blurring the line between truth and falsehood.

An example is the deepfake video falsely showing President Catherine Connolly withdrawing from the presidential race last October, which amassed over 160,0001 Facebook views before being removed.

GenAIโ€™s non-deterministic, stochastic architecture produces plausible output without regard for accuracy or truth.

This makes generative AI a societal disaster and a major threat to truth, democratic processes, information ecosystems, knowledge production, and the social fabric

Reads: For truth, democracy, and the rule of law to endure in the AI era, we need to cultivate an ecosystem of transparency and accountability. Yet governance by algorithms inherently places our digital public squares and democratic processes in the hands of those
building these systems in line with their political and profit-seeking agendas. Without real mechanisms in place, talk of transparency and accountability are empty gestures.

An internal Meta memo outlining plans to launch facial recognition in smart glasses โ€œduring a dynamic political environment where many civil society groups that we would expect to attack us would have their resources focused on other concernsโ€5 illustrates how those advocating for accountability are under-resourced, retaliated against, and targeted.

Large tech and AI companies, despite selling promises of innovation and societal benefit, monetize and undermine the very society they claim to serve. What is needed is not just regulation, but active enforcement.

Given the track record of tech giants, stricter regulation and enforcement is not โ€œantiโ€“freedom of speechโ€ or anti-competitiveness. It is one of the clearest ways governments can show they serve the public interest. After all, innovation that disregards truth and democratic processes risks undermining democracy itself.

"Stochastic Parrot" is such a good explainer for how LLMs work that Sam Altman's only rebuttal was claiming that humans are as well (which is patently false).

Reliability of LLMs as medical assistants for the general public: a randomized preregistered study - Nature Medicine In a randomized controlled study involving 1,298 participants from a general sample, performance of humans when assisted by a large language model (LLM) was sensibly inferior to that of the LLM alone ...

LLMs good performance on medical exams does not translate to accurate performance in real-world settings (preregistered n~1,300 study). This can't be explained by current standard benchmarks for medical knowledge & simulated patient interactions.
