It's he same problem as teleportation (star trek teleportation specifically)
They scan you, break you down, then transmit and create a new you.
Now if you re-order this a little.
Scan, transmit, create and then break down the original.
There are two of you, then the original is killed.
This shows that during the original process the first is scanned and killed, then a new person created. This is exactly how mind uploading would work in terms of continuity for the person being uploaded. (It's also why I would never ever use a teleporter.)
This is exactly what mind uploading is, they scan you and upload you. Creating a new you. Then you die and the other you lives on.
This is very clearly shown if you scanned and activated the copy before the first person died. Are you trying to imply that you would suddenly, as a single entity, be experiencing two perspectives at once? Because that just wouldn't be possible.
It is technically immortality for your memories, but not the specific physical instance of you.
