No, you're doing it wrong.
If you're going to object, you should do something more than
mere gainsaying, & provide reasoning using the correct word.
("Illogical" wouldn't apply to a singular factual claim.)
Surely if neurons are just chemicals, then with good enough nano-bots,
everything could be re-aligned the way it was.
You're sure of this.
I say no.
Even if nano-bots could alter chemicals at the atomic level, they
couldn't do this simultaneously, which would be necessary for an
organism which doesn't exist as separately functioning modules.
Death is a process with chemically irreversible effects at many levels.
So even if the two you's were identical, there would
not be a sense of 'I' shared by both.
Thus you would not be identical.
If we were hypothetically identical at one point in time, that
would end almost immediately because of different environments.
