Similarly, OP measures the system's ability to achieve its very top goals, not how hard these goals are. A system that wants to compose a brilliant sonnet has more OP than exactly the same system that wants to compose a brilliant sonnet while embodied in the Andromeda galaxy. Even though the second is plausibly more dangerous. So OP is a very imperfect measure of how powerful a system is.

I'm confused. A system that has to compose a brilliant sonnet and make sure that it exists in the Andromeda galaxy has to hit a smaller target of possible worlds than a system that wants to compose a brilliant sonnet, and doesn't care where it ends up. Achieving more complex goals require more optimization power, in Eliezer's sense, than achieving simple goals.
