If you delete the hardware and buy new hardware and write in the same weights its still the same LLM. If you delete your brain, get a new brain and put in the same weights in the neurons its a clone, its not you. We know what happens when we create a clone, the clones aren't the same person they are separate consciousness, so consciousness is tied to the hardware.
For example, if we have 5 identical clones down to the atoms of their brains, and send a message to the first and let him respond, then send the same message to the second together with the firsts response and let them add a new message etc. That is not one consciousness responding, thats 5 different consciousnesses responding, and that process doesn't connect them into a single consciousness. That is how LLM works, at best a single token generation is conscious, but that would be a less meaningful consciousness than a ringworm.
Your whole argument hinges on this, and I don't think it's true.
A clone is not what you describe, not even close. Clones are copies of DNA, not of the actual physical neuron structures.
If you were to vanish, and the next moment a perfect atom-for-atom, particle-for-particle, quark-for-quark copy appear in exactly the same place, I think that is you. As far as I know, that does happen every single planck second.
For it to be you, though, it needs to occupy the same space you were previously in. You can't copy your atoms 5 times over in 5 different locations; those aren't you, they're just similar. Like copying an LLM 5 times over to different hardware, seeding its RNG differently each time.
