That’s all a semantic argument. It seems obvious that if your brain is “wiped” as you put it, you are gone. Cloning or copying you doesn’t solve that, in the same way that you are not the same as your twin.

Your philosophical argument of “it’s complicated” is just muddying the water. When twins are born they are two different people. No one ever says “I’m so confused, there are two of the same people!”
