What is an observer?

We have long assumed that “an observer observes the world.”

But what if—

observation itself is not something we do, but something that only appears when certain conditions are met?

Two independent systems align only at specific moments.

Yet this alignment cannot be explained by causality, correlation, or measurement.

So who is observing?

Or rather—

does the observer emerge only when observation becomes possible?

What do you think about this perspective?

The observer emerges when it becomes entangled with the thing being observed. That's the best explanation I've ever heard on the topic, anyway. What appears to be an unexplainable phenomenon of the emergence of an observer is actually just a byproduct of lab equipment trying to measure something at a quantum scale, and inadvertently becoming entangled with it. And quantum entanglement is rather well understood.
