My personal philosophy on this is that the forces that shaped me and made me who I am will still exist after I'm gone, so it seems inevitable that some version of me will someday recombobulate by pure chance into some variation of what I represent.

Well, there's a theory that the Big Bang created both our universe which has an excess of matter and is moving forward through time; and, in the same instant, a mirror universe that has an excess of antimatter and is moving backward through time. So there's a mirror-you who, in a way, lived billions of years before you.
The next question then is: is this a cyclical event?

that all life necessarily shares.

Well that would be the physicalism/materialism hypothesis. Truth is we don't know. That's why it's called the "Hard Problem of Consciousness"

The scientific and philosophical communities are split into a few major camps:

Physicalism / Materialism: They believe consciousness is an emergent property of complex biological computation. Just like "wetness" emerges when you put hydrogen and oxygen together, consciousness emerges when you network enough neurons. (Though critics argue wetness is still just physical behavior, while consciousness is a whole new dimension).

Idealism / Non-Dual Perspectives: This flips the script entirely. Instead of consciousness being a product of the brain, the brain (and the whole physical world) is an appearance within consciousness. In this view, you don't have a conscious brain; the brain is a conceptual map appearing in the wide-open space of prior awareness.

Panpsychism: The view that consciousness is a fundamental building block of the universe, like mass or electrical charge, and complex brains simply channel or organize it rather than creating it from scratch.

Yeah I think consciousness is evidence in and of itself that the universe can organize into a higher order. It would be conceited to claim that because I obtained consciousness that means I can understand how that higher order functions. My consciousness will never reform exactly how it is now, but that is just a reflection of an ever changing universe.

Yeah. I think if we deprioritize individual consciousness then it comes easier to swallow (by the conscious mind...).

Obviously you shouldn't deprioritize others' minds. This is just a personal technique/cope.
