A place for all those who loathe AI to discuss things, post articles, and ridicule the AI hype. Proud supporter of working people. And proud booer of SXSW 2024.

The study appears to be saying something different from what the headline implies.
Basically it might be better to say that using an LLM doesn't require you to think as hard, you remember less of the essay, and when you go back to rewrite a previous essay without the LLM you have more trouble.
They also noted that for some people, using the LLM made them learn much better. Basically the difference between getting it to write for you and using it as a tool to structure information.
One reduced cognitive load from all sources, and the other reduced load relating to integrating different information sources.
Basically it was a proper study by people who knew what they were doing. They never actually said anything about rewiring.
