AI Bait & Switch:

bait: we’re gonna make an AI that can solve any problem experts could solve. it’s gonna transform the whole world.

switch: what we have actually made is fun and amazing, but rarely reliable and often makes mistakes – but ordinary people makes mistakes, too. So … AGI solved!

The reason why LLMs fail to play a game of chess, even though they can cite the rules from their training data, is an awesome example of what's stopping autonomous AI agents from being reliable.

Great discussion between @garrykasparov.bsky.social ♟️ and @garymarcus.bsky.social 🧠 on limits of GenAI.

The Atlantic podcast: AI and the Rise of Techno-Fascism in the United States

Kasparov: Yes. It’s very interesting, because it seems to me that, you know, what you are telling us is that machines know the rules because rules are written, but it still doesn’t know what can be done or cannot be done unless it’s explicitly written. Correct?

Marcus: Well, I mean, it’s worse than that. I mean, the rules are explicitly written, but there’s another sense of knowing the rules—which, we actually understand what a queen is, what a knight is, what a rook is. What a piece is. And it never understands anything. It’s one of the most profound illusions of our time that most people witness these things and attribute an understanding to them that they don’t really have.

Many people believe generative or any AI show signs of "intelligence", but Marcus attributes it to brute forcing with pattern recognition.

Finally! 🤩 Our position piece: Against the Uncritical Adoption of 'AI' Technologies in Academia:
doi.org/10.5281/zeno...

We unpick the tech industry’s marketing, hype, & harm; and we argue for safeguarding higher education, critical
thinking, expertise, academic freedom, & scientific integrity.
1/n

Abstract: Under the banner of progress, products have been uncritically adopted or
even imposed on users — in past centuries with tobacco and combustion engines, and in
the 21st with social media. For these collective blunders, we now regret our involvement or
apathy as scientists, and society struggles to put the genie back in the bottle. Currently, we
are similarly entangled with artificial intelligence (AI) technology. For example, software updates are rolled out seamlessly and non-consensually, Microsoft Office is bundled with chatbots, and we, our students, and our employers have had no say, as it is not
considered a valid position to reject AI technologies in our teaching and research. This
is why in June 2025, we co-authored an Open Letter calling on our employers to reverse
and rethink their stance on uncritically adopting AI technologies. In this position piece,
we expound on why universities must take their role seriously toa) counter the technology
industry’s marketing, hype, and harm; and to b) safeguard higher education, critical
thinking, expertise, academic freedom, and scientific integrity. We include pointers to
relevant work to further inform our colleagues.

Figure 1. A cartoon set theoretic view on various terms (see Table 1) used when discussing the superset AI
(black outline, hatched background): LLMs are in orange; ANNs are in magenta; generative models are
in blue; and finally, chatbots are in green. Where these intersect, the colours reflect that, e.g. generative adversarial network (GAN) and Boltzmann machine (BM) models are in the purple subset because they are
both generative and ANNs. In the case of proprietary closed source models, e.g. OpenAI’s ChatGPT and
Apple’s Siri, we cannot verify their implementation and so academics can only make educated guesses (cf.
Dingemanse 2025). Undefined terms used above: BERT (Devlin et al. 2019); AlexNet (Krizhevsky et al.
2017); A.L.I.C.E. (Wallace 2009); ELIZA (Weizenbaum 1966); Jabberwacky (Twist 2003); linear discriminant analysis (LDA); quadratic discriminant analysis (QDA).

Table 1. Below some of the typical terminological disarray is untangled. Importantly, none of these terms
are orthogonal nor do they exclusively pick out the types of products we may wish to critique or proscribe.

The group will also oppose any candidates perceived as slowing down AI development.
