Microsoft does research on cognitive decline in use of LLMs: "Nope."
Google does research on cognitive decline in use of LLMs: "Nope."
MIT does research on cognitive decline in use of LLMs: "Fine, I'll read your goddamn opinion on the matter."
Edited: The article is good, I recommend it. However, I find this "brain-only" approach to be too biased. Students and people in general cannot learn without external information. This approach assumes people have studied the topics beforehand and have knowledge in it, which causes biases on the study and beats the purpose of it, which is proving people do not learn using LLMs!
