Edit: There's a blog post on the failings of the study and the communication around it: Clickbait Neuroscience: Lessons from “Your Brain on ChatGPT” – Mind Brain Education

EEG revealed significant differences in brain connectivity: Brain-only participants exhibited the strongest, most distributed networks; Search Engine users showed moderate engagement; and LLM users displayed the weakest connectivity. Cognitive activity scaled down in relation to external tool use.

Over four months, LLM users consistently underperformed at neural, linguistic, and behavioral levels.

I mean this feels like an obvious result.

I'm glad scientists think otherwise, or we would still be living in the dark ages.

In other news, dark ages are a myth disproven by science.

Fair enough, let me rephrase that:

I’m glad scientists think otherwise, or we would still be living in the bronze age.

I'm sorry, that came off very passive-aggressive, I really shouldn't post at 3 am when I can sleep.

The whole dark ages, and golden ages thing is just very annoying, made up during the renaissance, in part as a useful tool to go "look how shit everything is, I will make it great and amazing like it was before", still a favorite to use by populists (in reference to whatever time is most suitable) and it's been repeated so much, it actually works, everyone kinda just accepted it. But then when you dig into it, the middle ages weren't really worse in terms of invention/art/etc. than the renaissance, nor was there this big stagnation after the decline of the roman empire, and people always made art, new inventions and great achievements, along with cruelty, bloodshed and other awful things. But then this has been a relatively recent shift in historical research, so not that well known

Well for one the historical field is part of the humanities and for second dark ages are certainly a thing just not the medieval dark age. The Greek dark age is most certainly a thing for example.
