I share your skepticism of any consciousness being able to exist in a machine (save one caveat, below).
Even the most advanced AI model could - at best - execute a series of actions based on all previously ingested data, with the origin of its “directive” (and existence) being a derivative of human consciousness x
At the best, it could carry out these tasks so convincingly well that humans may *believe* that it’s conscious. But by its very nature, by definition, it cannot be more than mimicry, originally seeded by human thought. It wouldn’t “believe” it is conscious because there’s no one inside to believe anything. All it can do is express data.
The exception — and I consider this to be a profoundly beautiful understanding of existence — is if all of “being” is made of deterministic matter and energy. Here’s why that is cool: we ARE conscious. Simply sit for a moment and watch your breath. YOU are there. YOU might not be anything you think (body, desire, thought, etc.) but you are here now.
From that “first-principles” truth, it’s not hard to imagine (or conclude) that all matter - all energy - is related to (or suffused with or made up of) this consciousness. It fits what ancient meditating sages thought. It fits what religious figureheads (minus the organized religion) said. It fits with quantum physics.
If you are everything and everything is you, I find that peace in existing comes easily. My two sats 😉🫂
