MIT Researchers Just Discovered an AI Mimicking the Brain on Its Own

You will be shocked to learn that the headline is overblowing what occurred.

My interpretation of the article is that they studied a bunch of neural networks (GPT, etc) and found some of them seemed to behave similarly to real brains.

They didn't create their own NN that developed similar structure, nor was it a matter of new behavior from a NN, just an analysis of pre-existing implementations.

Isn’t it called a “Neural” Net for the same reason, I remember starting an ML book describe how a brain works and how we mimic it? In other words did they just prove that and existing ML algo is doing just that? Is it headlines because its MIT?
