We did not know about the Memory Worlds when we first went to space. We spread out and colonized our Solar System because it was there and because we wanted to see it all. We wanted to plant our flags on alien worlds and then around alien stars. We did it because there is a drive, a wanderlust deep in our genetic code. We will always believe that the grass is greener on the other side, and if it is not, then we will water it until it is. The AIs left Earth and built their Memory Worlds to save us all. We left Earth and built our colonies to find out who we were. To find out what we could do. Who we could be. To see things no human eye had seen before. We would have died on Earth without that drive to see what is out there. And we would have died out there without the AI’s drive to save everything. It is perhaps the final irony that we saved each other, and that knowledge is forever saved in the Memory Worlds should we ever forget it.
