We are about to develop AI assistents and possibly AI who teaches. This AI might only be able to teach in simple terms and be asked the usual questions.
Inspired by this. Why could not we humans with our advanced brain have built in biological mini intelligences. Maybe there exists intelligence as programs from other animals from our heritage in our brain.
The purpose of this special intelligence would be to train the rest of the brain. So why is there not only such intelligence. One guess would be that the trained brain can connect skills from different programs and make connections that the biological programs themselves can not do.
