I’ve been watching the TV series Pantheon and I really like it, but this tiny aspect is something I can’t quite grasp. So these people have their minds uploaded to the cloud - and they make a point to state that they’re still “them” - alive, real, authentic. But would it really be like that? The process is brain mapping, so essentially they just make a perfect clone of your brain/mind and run it digitally. But it’s still just a simulation. A perfect clone is still just a clone. The original person is gone. I don’t see the “continuity” aspect.
An even deeper mind fuck is that the you that’s reading this this second, might have just come into existence with all the memories you have now. There’s no way to know how volatile truth and consciousness really is in our universe.
Last Thursdayism is a philosophical idea that the universe was created last Thursday, but appears to be much older.
Next Thursdayism is a philosophical idea that the universe will be created next Thursday, appearing to be much older.
Yeah, there are indeed all sorts of weird hypothetical but possible scenarios out there. You might actually be a Boltzman brain and not even know it.
But I prefer to focus on what we can actually measure and observe. And we do know that consciousness ceases each night. Even if we count dreaming as consciousness, you conscious experiences is not a continuous thing. If “you” are simply your consciousness, then you die every night.
