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).
Sure, then all we need is good regulators to ensure everyone hobbles their extremely useful AI in this manner.
Unfortunately this topic is impossible to get traction on. We are probably better off debating which political party sucks more (Hint: it starts with a consonant).
