I think a big reason why uploads may be much worse than regular life is not that the brain scan will be not good enough but that they won’t be able to interact with the real world like you can as a physical human.
Edit: I guess with sufficiently good robotics the ems would be able to interact with the same physical world as us in which case I would be much less worried.
I’d say even simply a simulated physical environment could be good enough to be indistinguishable. As Morpheus put it:
What is real? How do you define ‘real’? If you’re talking about what you can feel, what you can smell, what you can taste and see, then ‘real’ is simply electrical signals interpreted by your brain.
Of course, that would require insane amounts of compute, but so would a brain upload in the first place anyway.
