Just a quick thought after watching the Observer Theory session:

In order to compute the universe needs to first observe its current state. For example, in order to compute 0+1=1 or 4+1=5, it needs first to observe the initial state - 0 or 4 - and then the addition happens to compute the result. So every single computation is a result of a corresponding observation. One doesn’t exist without the other.

In a way, observation is like adding zero, for example, 0+0=0 or 4+0=4. Zero is added before each computation.

So the universe is self-observing from the very beginning. As the universe grows, the number of computations and observations grow, too. For example, observing the cosmic microwave background by multi-computational observers like us.
