Why your brain needs a gym in the age of AI

Transcript

Have you ever thought about why gyms even exist? For most of history nobody needed one because life itself was the workouter. Then, machines started doing the heavy lifting for us and suddenly we had to pay money to lift heavy things on purpose. And I think AI is about to do the same thing to our brains, only much faster. Chat GPT got to 100 million people in about 2 months. Now look at London's taxi drivers. To get a license, they have to memorize around 25,000 streets, which takes 3 to 4 years and only about half of them even make it. Scientists followed 79 trainees and scanned their brains the whole way through. And the ones who passed actually grew the part of the brain that handles navigation. And the ones who didn't make it showed no change at all. So your brain literally changes based on what you make it do. And AI is offering to do almost all of it for you. And look, I use AI every day and not saying stop. I'm just saying if the machine does the heavy lifting again, your mind needs a gym the same way our body is dead.
