Ok, so, do you actually have any examples that fall outside the 3 categories:
1:Powerful+Safe
2:Powerful+Unsafe
3:Not very powerful such that it doesn't matter so much if they're safe or unsafe.
Examples of what? Of hypothetical intelligent minds? I feel like there are examples all over fiction; consider genies themselves, which often grant wishes in a dangerous way (but you can sometimes get around it by speaking carefully enough). Again, I agree that some genies are never safe and some are always safe, but it's easy to imagine a genie which is safe if and only if you specify your wish carefully.
Anyway, do you concede the point that EY's article contains no arguments?
