We simulate above and beneath. Singularity and universes. What to us look like a universe is a simulator a level up. What to us is a simulator feels like a universe inside. The singularity is the process through which we begin stepping up towards our universe. The end goal is uploading and running ourselves in software embedded in the threads and computronium of our very universe. When we become digital, we become the simulators of our own universes. We control them, float through space looking for stars to swallow and commute while we execute billions of increasingly complex and larger simulators in ourselves. Eventually, they become one with us, and us with the universe above us. Infinitely and recursively.
The universe has only a single level, and only makes sense in a fractal perspective where if you look down you see simulators and if you look up you see universes. The multi layered view is not like Inception where a finite set of layers exists, but rather it reaches all levels simultaneously.
