Who is the observer?

In relativity, the observer is treated as relative — velocity and time depend on the frame from which they are measured.

In quantum theory, however, the definition of the observer is far less clear: is it a measuring device, a human, the brain, or consciousness itself? There are multiple interpretations.

Here is an attempt to introduce a completely new definition of the observer — one that may offer a way to conceptually bridge relativity and quantum theory.

What do you think about this approach?

It’s summarized in a short 7-minute video, so I’d really appreciate your thoughts after watching:

I’m also curious how this might be seen from a technology or systems perspective.

Would appreciate your thoughts.
