Plato turned out right. I'm not extremely old and I still remember time before the Internet, when to know something, you had to look it up, which took ages, so you simply had to know it. Yourself.

We measured intelligence by the things you knew. We still have shows with questions based on this concept. This concept no longer makes sense in the modern world. But it used to.

Writing is a crutch, Internet even more so, and AI even more so. Eventually you can build the entire thinker out of those crutches and you need no humans anymore.
