I think the difference here is that we share our bodies with the copy and share our memories. The difference between us at night and us in the morning is small.

I think the difference here is that we share our bodies with the copy and share our memories. The difference between us at night and us in the morning is small. A copy in the cloud doesn't pass memories on to us when it sleeps and it's experience is very different. It's digital and could technically have a billion instances with no experience sync between them. Which one is 'you' then? The best way to go about this IMO, is nano bots first augmenting the brain, connecting to the cloud, then replacing the brain slowly and introducing syncing consciousness when online. Replace a little every night and then it would still be you IMO since you're replicating most closely what the brain already does.
