Unsurprisingly we don't read similar opinion pieces about "the right" while the US gouvernement unplugs vaccines research.

(critically as embedded in a larger background knowledge and experience, not as being dismissive). "Ne soyez pas le secrétaire des malades".
Which could be modernized as "don't be a statistical parrot"

He laid down principles of clinical examinations that, to me, highlight all the complexity and non reducibility of clinical practice. Notably the tension between 2 imperatives 1) be aware of the uniqueness of each patient ("individualité maladive") and 2) assess critically what they report

This is a critical point. One could say that inferring what questions are relevant in a clinical examination is just another instance of pattern detection. I believe it misses the core of what clinical skills actually are. In psychiatry the teaching of JP Falret (1874) is still highly relevant

They also spread the message to kids that smoking is an adult's choice, which is both subtly incitative and carefully avoiding public health issues.
Similarly the message that only specialists should use llms bypasses the existential question of why should my google search result in a word salad ?

In the brain causal interventions on a specific region or circuit does not imply that this circuit is a module (= encapsulated system dedicated to this function whose output would be indépendant from other modules)

Lesion studies can demonstrate the specificity of function but the limits can be more and more fuzzy as the scope increases. A general theory of human physiology would require transversal approaches (e.g. ontogeny) in addition to individual systems characterisation

I like the analogy with organs but it can be misleading as looking for modules as physical entities would be akin to phrenology. But i agree that describing something as a module (e.g. immune system) does not imply an explicit design. However i think question remains about the limits of modularity

Fodor was very critical of this theory as modularity was a relevant description for low level processes. I think the current debate in neuroscience is about that : can we find arguments for low level functions that are completely encapsulated from other modules ?

In my understanding the defining characteristic of modularity is functionnal encapsulation. Some have argued that the mind is massively modular i.e. no transversal process, and that really sounds unnatural and more like software engineering

I'd say the term "model" is better suited than "tool". I see why they can be framed as bad models of language from an explanatory cognitive perspective, but i think they are not even bad tools

But companies continuously claim the inevitability of it and that safeguards are possible to prevent such use cases. I'm saying that taking full accountability is the only logical consequence. Otherwise they have to admit they cannot control shit and remove it entirely.

I think complying with the law, especially regarding child porn, is a pretty low standard already. But is it possible is the question ideed. I believe it's not and we don't need to pollute already toxic social networks with garbage generating bots.

It's either (1) safeguarding llms is not possible and we should a) ask if they are necessary everywhere b) regulate them ; or (2) safeguarding is possible (as llms are marketed) and companies should be accountable for not implementing it correctly. They can't have it both ways.

This one is conceptually similar to the approximation one: you can't move all the tractability burden to evolution. Evolution of intractable rationnality is tractable though !

I first encoutered the tractable cognition thesis in this book. I often return to it with pleasure. This was an excellent first exposition to the topic, especially for someone familiair with experimental cog sci but with no background in computer science cognitionandintractability.com
