Another frame: If alignment turns out to be easy, then the default trajectory seems fine (at least from an alignment POV. You might still be worried about EG concentration of power).
If alignment turns out to be hard, then the policy decisions we make to affect the default trajectory matter a lot more.
This means that even if misalignment risks are relatively low, a lot of value still comes from thinking about worlds where misalignment is hard (or perhaps “somewhat hard but not intractably hard”).
