To the point: if AGI can't pose a danger, because its hands are tied, that's wonderful! Then we have more time to work of FAI. FAI is not about superpowerful robots, it's about technically understanding what we want, and using that understanding to automate the manufacturing of goodness. The power is expected to come from unbounded automatic goal-directed behavior, something that happens without humans in the system to ever stop the process if it goes wrong.
