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 recently used AI to make a plugin using a programming language I’ve never used before.
When working on similar projects in the past, I get to the end with a new understanding of the language and its capabilities.
This time, I think it took about 10% longer, was no easier overall (although each step seemed easier to start), and I feel like I still have basically no understanding of the language or its features.
If I were to start over, I’d still have to start learning from the beginning. AI has saved me no time at all, and the plugin still has plenty of subtle bugs I need to remove by hand.
