Human memory is the very basis of civilisation. It is the fundamental ingredient responsible for all science, technology and culture on the planet. But this source of empowerment can also become a source of enslavement. Memory is like a doorway. Doors can open, but they can also close. If doors open, you experience them as wonderful. If they keep slamming in your face, they can be horrible.
Mere intelligence cannot produce civilisation. The transmission of memory from generation to generation enables us to build a foundation and forge ahead. Otherwise, we would be doomed to keep reinventing the wheel.
