Another thing to keep in mind is that, for many unethical people, there's a limit to their unethical approaches. A lot of them might be willing to lie to get a promotion but wouldn't be willing to, e.g., lie to put someone to death. I'm not convinced that an unethical AI would have this nuance. Basically, on some level, you can still trust a lot of unethical people. That may not be true with AIs.

I'm not convinced that the AIs do fail the same way people do.
