Well, the way I've seen it explained, seems like it's similar to being able to dereference some object locally to read a value (observation) but not having access to that global state between the two variables to write it (we don't know yet at least).

The problem being that dereferencing (observing) is a mutating operation.

So, maybe we will find something some day. A bit of a professional deformation :o)

Science evolves.
