         | The easiest way to wrap your head around is to:
         | 
         | 1. Abandon for a moment the idea that we are special
         | 
         | 2. Imagine what the most simplified agent that "experiences"
         | things would look like. For example a simple machine that
         | observed am experiment and reduces it into a simple "do I see
         | interference bands or do I see only one band?" and records it
         | to some simple memory.
         | 
         | 3. Let the wave in superposition interact with the machine and
         | compute what happens to the machine now that it is itself
         | entangled with the wave
         | 
         | 4. Very hard math
         | 
         | 5. The machine is in a superposition state of various state,
         | each observing the wave collapse

       | like these. They put the effort into making analogies and
       | comparisons for even the most esoteric theoretical constructs
       | like the ones in this article. I can't judge if they're
       | _accurate_ , owing to not being a theoretical physics Ph.D., but
       | it's always an entertaining read.
