Interesting finding: not using the brain leads to a whack brain. Or: we had 10 people play tennis and ten watch a robot play tennis. The people who played tennis stimulated more muscles in their arm while playing tennis than the people who watched the robot play tennis.
It felt indeed that what the paper said is just: "If you are using a tool in order to make hard-work feel more easy... then your brain is not working as much"
Yea, the title too is click bait, and based on the abstract, the whole study is click bait. "Ai = Bad". If I use an llm to do things, then it frees up time for me to use my brain in other ways, or if I outsource jobs to my llm, that should allow me to focus on higher-level tasks. It's just a lame experiment, unless there's more in the paper that I missed since I just read the abstract.
