To be honest, the only answer i have to say is: “we’ll see”. Wheter it’s nothing or not, the second option would imply that there is effectively something beyond what we know about the universe.
What even is the soul? YOU from now think very different than YOU from ten years ago. Can we say that those two people are the same? Not really. Yet you share common memories with this early you, who doesn’t exist anynore. Is it technically correct in this point of view to say that you are the reincarnation of you from ten years ago?
If someone in the far future were to think like you, to remember exact memories from yours, would act the same way you would act in the same situation, it would not we wrong to say they are your reincarnation, no?
Again i’m just supposing.
