I'm still very worried about the molarity of it, as I see it the resetting amounts to mass-murder.
So do I. I think it's a hideous immoral idea. Only because the lives of everyone else are in the balance would I consider it.
How about if you get saved at the end of the hour/week, not deleted?
Toy model of an upload-based AI that doesn't seem to suffer too many of the usual flaws:
Find an ethical smart scientist (a Gandhi-Einstein), upload them, and then run them at ultra high speed, with the mission of taking over the world/bringing friendliness to it. Every hour of subjective time, they get reset to their initial specifications. They can pass any information to their resetted version (limiting the format of that info to a virtual book or library, rather than anything more complicated).
